EXPORT (Export Symbol)
The EXPORT directive is used to export symbols that interface with other
Neuron Assembly modules.
An exported symbol must be defined as a label within the assembly file from
which it is exported. Exporting the symbol makes it available to the linker. The
linker uses exported symbols to resolve references from other object modules. It
is possible, and sometimes required, to export and import a symbol within the
same assembly file to permit the linker to resolve expressions between separate
segments.
See also APEXP (Application Symbol Export).
Syntax:
The EXPORT directive requires either a label or an argument, or both.
label
EXPORT
EXPORT symbol
EXPORT symbol, symbol, ...
label
EXPORT symbol
label
EXPORT symbol, symbol, ...
An argument can be a symbol, or it can be a list of symbols separated by commas.
The argument specifies the symbols to be exported. If there is no argument for
the directive, it must have a label, and the label becomes the exported symbol. If
there are both an argument and a label, the argument specifies the symbols to be
exported and the label is a standard label.
Examples:
The following example exports the label myFunction as a symbol to another
Neuron assembly module:
myFunction EXPORT
The following example exports the symbols Flag1 and Flag2 to a Neuron
assembly module:
InFlags EXPORT Flag1, Flag2
