Importing and exporting of symbols is a feature that is very useful when your project spans many source-files and for example you
need to jump to a routine defined in another file.
| Command | Meaning |
| IMPORT (or XREF) label[,label,...] | This instructs the assembler to define label as if it were present in the current file but leave the address calculation to the linker. |
| EXPORT (or XDEF) label[,label,...] | The assembler will make label accessible to other files during the link process. |
| GLOBAL label[,label,...] | If label is defined during the assembly it will be exported, if not it will be imported. Handy (very!) for include-files. |
