1.1.9 $DEFINE : Dene a symbol

The directive

denes the symbol name. This symbol remains dened until the end of the current module (i.e. unit or program), or until a $UNDEF name directive is encountered.

If name is already dened, this has no eect. Name is case insensitive.

The symbols that are dened in a unit, are not saved in the unit le, so they are also not exported from a unit.
