* source/compiler/harbour.sly
! Optimized __GETA() support, and changed it to be implementated identical to Clipper.
/* Clipper passed a bGet Block which refrences the Base Array Variable and not the Variable itself.
Clipper passes NIL instead of bGet block if the Base Array is MACROVAR or MACROTEXT.
Clipper does not optimize "&Macro" to Macro, but Harbour does! */
* source/rtl/tgetint.prg
* __GETA() Changed 1st parameter aVar to bGetArray and logic to get the Base Array if bGetArray is NIL
/* Optimized to not use macro if possible (most cases) even if the GetArray is a macro. */
* tests/testget.prg
+ Added additional test.
