-<h1>Fixed‐point Expressions</h1>
-<p>Fixed point constants are basically normal 32-bit constants where the upper 16 bits are used for the integer part and the lower 16 bits are used for the fraction (65536ths). This means that you can use them in normal integer expression and indeed some integer operators like plus and minus don't care whether the operands are integer or fixed-point. You can easily convert a fixed-point number to an integer by shifting it right 16 bits. It follows that you can convert an integer to a fixed-point number by shifting it left.</p>
-<p>Some things are different for fixed-point math though. Which is why you have the following functions to use:</p>

-<h1>Integer and Boolean expressions</h1>
-<p>An expression can be composed of many things. Expressions are always evaluated using signed 32-bit math.</p>
-<p>The most basic expression is just a single number.</p>
-<h2>Numeric Formats</h2>
-<p>xAsm has a number of numeric formats.</p>
-<ul>
- <li>Hexadecimal: $0123456789ABCDEF. Case-insensitive
- <li>Decimal: 0123456789
- <li>Octal: &01234567
- <li>Binary: %01
- <li>Fixedpoint (16.16): 01234.56789
- <li>Character constant: "ABYZ"
- <li>Gameboy graphics: `0123
-</ul>
-<p>The last one, Gameboy graphics, is quite interesting and useful. The values are actually pixel values and it converts the “chunky” data to “planar” data as used in the Gameboy.</p>
-<pre>DW `01012323</pre>
-<p>Admittedly an expression with just a single number is quite boring. To spice things up a bit there’s a few operators you can use to perform calculations between numbers.</p>
-<h2>Operators</h2>
-<p>A great number of operators you can use in expressions are available (listed in order of precedence):</p>
-<table>
- <caption>Operators</caption>
-<thead>
-<tr>
- <th scope="col">Operator</th>
- <th scope="col">Meaning</th>
-</tr>
-</thead>
-<tr>
- <td>( )</td>
- <td>Precedence override</td>
-</tr>
-<tr>
- <td>FUNC()</td>
- <td>Functioncall</td>
-</tr>
-<tr>
- <td>~ + -</td>
- <td>Unary not/plus/minus</td>
-</tr>
-<tr>
- <td>* / %</td>
- <td>Multiply/divide/modulo</td>
-</tr>
-<tr>
- <td><< >></td>
- <td>Shift left/right</td>
-</tr>
-<tr>
- <td>& | ^</td>
- <td>Binary and/or/xor</td>
-</tr>
-<tr>
- <td>+ -</td>
- <td>Add/subtract</td>
-</tr>
-<tr>
- <td>!= == <= >= < ></td>
- <td>Boolean comparison</td>
-</tr>
-<tr>
- <td>&& ||</td>
- <td>Boolean and/or</td>
-</tr>
-<tr>
- <td>!</td>
- <td>Unary Boolean not</td>
-</tr>
-</table>
-
-<p>The result of the boolean operators is zero if when FALSE and non-zero when TRUE. Thus it is legal to use an integer as the condition for <a href="if.htm">IF</a> blocks. You can use symbols instead of numbers in your expression if you wish.</p>
-
-<p>An expression is said to be constant when it doesn't change its value during linking. This basically means that you can't use labels in those expressions. The instructions in the macro-language all require expressions that are constant.</p>

-<p>A funky feature is <b>{symbol}</b> withing a string. This will examine the type of the symbol and insert its value accordingly. If symbol is a string symbol the symbols value is simply copied. If it's a numeric symbol the value is converted to hexadecimal notation and inserted as a string.</p>-<p><strong>HINT:</strong> The <b>{symbol}</b> construct can also be used outside strings. The symbols value is again inserted as a string. This is just a short way of doing "{symbol}".</p>-<p>Whenever the macro-language expects a string you can actually use a string expression. This consists of one or more of these function. Yes, you can nest them. Note that some of these functions actually return an integer and can be used as part of an integer expression!</p>

-<h1>FAIL, WARN</h1>
-<p>FAIL and WARN can be used to terminate the assembling process if you wish to do so. This is especially useful for macros that get an invalid argument. FAIL and WARN take a string as the only argument and they will print this string out as a normal error with a linenumber.</p>
-<p>FAIL stops assembling immediately while WARN continues after printing the errormessage.</p>

-<h1>Labels</h1>
-<p>One of the assembler’s main tasks is to keep track of addresses for you so you dor’t have to remember obscure numbers but can make do with a meaningful name, a label.</p>
-<p>This can be done in a number of ways:</p>
-<pre>GlobalLabel
-AnotherGlobal:
-.locallabel
-.yet_a_local:
-ThisWillBeExported:: ;note the two colons</pre>
-<p>This is very similar to other assemblers. Local labels are only accessible within the scope they are defined. A scope starts after a global label and ends at the next global label. You may or may not have seen the <b>::</b> feature before. It declares a normal global label but does an <a href="export.htm">EXPORT</a> at the same time.</p>
-<p>Labels will normally change their value during the <a href="../link.htm">link process</a> and are thus <em>not</em> constant.</p>

- <link rel="stylesheet" type="text/css" href="../style.css">

-<body>
-<h1>MACRO, ENDM</h1>
-<p>One of the best features of an assembler is the ability to write macros for it. Macros also provide a method of passing arguments to them and they can then react to the input using IF-constructs.</p>
-<pre>MyMacro: MACRO
- ld a,80
- call MyFunc
- ENDM</pre>
-<p>The above example is a very simple macro. You execute the macro by typing its name.</p>
-<pre> add a,b
- ld sp,hl
- MyMacro ;This will be expanded
- sub a,87</pre>
-<p>When the assembler meets MyMacro it will insert the macrodefinition (the text enclosed in <b>MACRO/ENDM</b>).</p>
-<p id="labelsuffix">Suppose your macro contains a loop.</p>
-<pre>LoopyMacro: MACRO
- xor a,a
-.loop ld [hl+],a
- dec c
- jr nz,.loop
- ENDM</pre>
-<p>This is fine. That is, if you only use the macro once per <a href="labels.htm">scope</a>. To get around this problem there is a special label string equate called <b>\@</b> that you can append to your labels and it will then expand to a unique string.</p>
-<p><b>\@</b> also works in <a href="rept.htm">REPT-blocks</a> should you have any loops there.</p>
-<pre>LoopyMacro: MACRO
- xor a,a
-.loop\@ ld [hl+],a
- dec c
- jr nz,.loop\@
- ENDM</pre>
-<h2>Arguments</h2>
-<p>I’d like <i>LoopyMacro</i> a lot better if I didn’t have to pre-load the registers with values and <em>then</em> call it. What I’d like is the ability to pass it arguments and it then loaded the registers itself.</p>
-<p>And I can do that. In macros you can get the arguments by using the special macro string equates <b>\1</b> through <b>\9</b>, <b>\1</b> being the first argument specified on the calling of the macro.</p>
-<pre>LoopyMacro: MACRO
- ld hl,\1
- ld c,\2
- xor a,a
-.loop\@ ld [hl+],a
- dec c
- jr nz,.loop\@
- ENDM</pre>
-<p>Now I can call the macro specifying two arguments. The first being the address and the second being a bytecount. The macro will then reset all bytes in this range.</p>
-<pre> LoopyMacro MyVars,54</pre>
-<p>You can specify up to nine arguments when calling a macro. Arguments are passed as string equates. There’s no need to enclose them in quotes. Parameter passing has changed a bit since v1.03 in that an expression will not be evaluated first but passed directly. This means that it’s probably a very good idea to use brackets around \1–\9 if you perform further calculations on them. For instance if you pass 1+2 as the first argument and then do <code> PRINTV \1*2</code>
-you will get the value 5 on screen and not 6 as you might have expected.</p>
-<p>Note that a colon (:) following the macro-name is required. Macros can't be exported or imported. It's valid to call a macro from a macro (yes, even the same one).</p>

-<p>The PURGE command allows you to completely remove a symbol from the symbol table as if it had never existed. USE WITH EXTREME CAUTION!!! I can’t stress this enough but you <em>seriously</em> need to know what you are doing. DON’T purge symbol that you use in expressions the linker needs to calculate. In fact, it’s probably not even safe to purge anything other than string symbols and macros.</p>

- <title>xAsm SECTION</title>
- <link rel="stylesheet" type="text/css" href="../style.css">
-</head>
-<body>
-<h1>SECTION</h1>
-<p>Before you can start writing code you must define a section. This tells the assembler what kind of data follows and if it is code where to put it.</p>
-<pre>SECTION "CoolStuff",ROMX</pre>
-<p>This switches to the section called <b>"CoolStuff"</b> (or creates it if it doesn't already exits) and it defines it as a code section. All sections within a sourcefile must be identified by a <em>unique</em> name.</p>
-
-<p>Possible section types are as follows:
-
-<dl>
- <dt>ROM0</dt>
- <dd>A ROM section. Mapped to memory at $0000–$3fff.</dd>
-
- <dt>ROMX</dt>
- <dd>A banked ROM section. Mapped to memory at $4000–$7fff. Valid banks range from 1 to 511.</dd>
-
- <dt>VRAM</dt>
- <dd>A banked video RAM section. Mapped to memory at $8000–$9fff. Can only allocate memory, not fill it. Valid banks range from 0 to 1.</dd>
-
- <dt>SRAM</dt>
- <dd>A banked external (save) RAM section. Mapped to memory at $a000–$bfff. Can only allocate memory, not fill it. Valid banks range from 0 to 3.</dd>
-
- <dt>WRAM0</dt>
- <dd>A general-purpose RAM section. Mapped to memory at $c000–$cfff. Can only allocate memory, not fill it.</dd>
-
- <dt>WRAMX</dt>
- <dd>A banked general-purpose RAM section. Mapped to memory at $d000–$dfff. Can only allocate memory, not fill it. Valid banks range from 1 to 7.</dd>
-
- <dt>HRAM</dt>
- <dd>A high RAM section. Mapped to memory at $ff80–$fffe. Can only allocate memory, not fill it. NOTE WELL: if you use this method of allocating HRAM the assembler will NOT choose the short addressingmode in the LD instruction because the actual address calculation is done by the linker! If you find this undesirable you can use <a href="rs.htm">RSSET/RB/RW</a> instead or use the LDIO mnemonic. The address calculation is then done by the assembler.</dd>
-</dl>
-
-<p>The following deprecated section names are aliases for some of the above sections:
-
-<dl>
- <dt>HOME</dt>
- <dd>Alias for ROM0.</dd>
-
- <dt>CODE</dt>
- <dt>DATA</dt>
- <dd>Alias for ROMX.</dd>
-
- <dt>BSS</dt>
- <dd>Alias for WRAM0.</dd>
-</dl>
-
-<p>Due to quite a lot of emails requesting an ORG directive you can now add an address to the sectiontype for the Gameboy:</p>
-<pre>SECTION "CoolStuff",ROM0[$1234]</pre>
-<p>This will force the section to address $1234. This also works with the other sectiontypes. For ROMX sections the linker will then place the section in any bank at the address you specify. If you also want to specify the bank you can do:</p>
-<pre>SECTION "CoolStuff",ROMX[$4567],BANK[3]</pre>
-<p>And if you only want to force the section into a certain bank, and not it's position within the bank, that's also possible:</p>
-<pre>SECTION "CoolStuff",ROMX,BANK[7]</pre>
-<p><strong>HINT:</strong> If you think this is a lot of typing for doing a simple ORG type thing you can quite easily write an intelligent macro (called ORG for example) that uses <a href="expr_str.htm">\@</a> for the sectionname and determines correct sectiontype etc as arguments for SECTION</p>

- <li> [n16]/[$FF00+n8]
- <li> [$FF00+C]/[C]
-</ul>
-<p>The assembler will intelligently decide between <b>[n16]</b> and <b>[$FF00+n8]</b> in the LD instruction. Note however that if you use any <a href="symbols.htm">constant symbols</a> in the expression they had better be defined before the instruction or your symbol-table may become mangled. Also worth noting is that it will only ever select the short $FF00 mode when you use constant symbols. NOT if you use symbols defined in a <a href="section.htm">HRAM section</a>. As this defies the whole point of implementing the HRAM sectiontype I've added the LDIO mnemonic. It works like the LD instruction but it will ALWAYS generate the $FF00+ form and it will also automatically logically AND the expression with $FF if it is relocatable. Which is what you want. Trust me ;)</p>

- <li>Example filenames have been changed to adhere to Jeff Frohweins proposed standard.
-</ul>
- <p>General fixes:</p>
-<ul>
- <li>RGBLink knows about big and little endian. Plus it can do range checking on intermediate results in an expression. This is necessary to support
-different types of CPUs.
- <li>RGBLink <em>didn’t</em> know about the special PC symbol “@” so if you used it more than once per sourcefile in an expression the linker had to resolve, things would go horribly wrong.
- <li>There was a bug in the macro parameter passing. Any whitespace after the last parameter would be appended to the last parameter. Reported by Jeff Frohwein.
- <li>A section stack has been implemented. Look up POPS and PUSHS in the
-manual. Jeff Frohwein’s doing again.
- <li>OPT command added for defining and changing some options while assembling.
- <li>You can now define which characters are used for the Gameboy graphics integer (`) using the commandline or the new OPT command. Cool idea by (surprise surprise) Jeff Frohwein.
- <li>Also, an option stack has been added. Look up POPO and PUSHO in the manual.
- <li>Fixed yet another line number bug reported by Jeff Frohwein (when will this guy leave me alone? ;)

-<h2 id="usage">Usage</h2>
-<pre> xlink [options] linkfile</pre>
-<p>Options are preceded by a hyphen (-) and go as follows:
-<pre> h : Short help text
- m<b>mapfile</b> : Write a mapfile
- t : Output target:
- tg : Gameboy <a href="#operationtg">ROM image</a> (default)
- ts : Gameboy <a href="#smallmode">Small mode (32kB)</a> ROM image
- tp : <a href="#psion2">Psion2</a> relocatable module
- z<b>HX</b> : Set the byte value (hex format) used for uninitialised data (default is ? for random)
-</pre>
-<h2 id="linkfile">The Linkfile</h2>
-<p>A linkfile is used to tell <B>xLink</B> which objects to include and what the outputname should be. It is in plain ASCII-format.
-<pre> # Linkfile for foobar.gb
-
- [Objects]
- foo.obj
- bar.obj
-
- [Libraries]
- mylib.lib
-
- [Output]
- foobar.gb</pre>
-<p>A line starting with # is ignored.
-<p>If you use libraries they will only be included if one of the objects actually reference them. This works on a SECTION level and not on a module level. This means that when you write libraries you can put each subroutine in its own SECTION so only the relevant bits are included.
-<h2 id="operationtg">Operation for Gameboy (-tg)</h2>
-<p><a href="asm.htm#sections">Sections</a> created with <b>ROM0</b> in the assembler are placed in the GB bank #0 (the fixed bank $0000-$3FFF) in the order they are loaded from the objectfiles specified in the linkfile. So you want the first file in the linkfile to contain your header. <b>ROMX</b> sections are placed in <em>any bank other than #0</em>. This means you have absolutely <em>no</em> control over which sections goes where. This insures minimal slack (unused bytes) at the end of each bank in the image.
-<p>Currently the linker doesn't calculate the GB checksums.
-You must use <a href="fix.htm">RGBFix</a> to do this.
-
-<h3 id="smallmode">Operation for Gameboy small mode (-ts)</h3>
-<p>Small mode forces all <b>ROMX</b> sections to be of type <b>ROM0</b> and increases the <b>ROM0</b> section size from 16kB to 32kB. This also means that <b>ROM0/ROMX</b> sections are written to the final image in the order you have specified on the command line.
-<p>Currently the linker doesn't calculate the GB checksums. You must use <a href="fix.htm">RGBFix</a> to do this.

-<h2 id="background">Background</h2>
-<p>I developed the RGB0 fileformat mainly because I needed a suitable dataformat to hold the output from <a href="asm.htm">xAsm</a> that was powerful to accomodate all the features I needed and also would make it easy for me to add new ones. The reason for documenting it is so people can write converters between it and other formats. Perhaps even develop other compilers for it?</p>
-<p>The RGB1 fileformat saw the light of day with the V1.02 of the old RGBDS release because of the addition of fixed sections.</p>
-<p>The RGB2 fileformat emerged because I needed to add support for big endian CPUs.</p>

-<h2 id="rpn">Rpn Data</h2>
-<p>Expressions in the objectfile are stored as <abbr title="Reverse Polish Notation">RPN</abbr>. This is an expression of the form “2 5 +”. This will first push the value “2” to the stack. Then “5”. The “+” operator pops two arguments from the stack, adds them, and then pushes the result on the stack, effectively replacing the two top arguments with their sum. In the RGB format RPN expressions are stored as <b>BYTE</b>s with some bytes being special prefixes for integers and symbols.</p>
