Description

This function enables or disables some features of the macro compiler. The Harbour is extending the macro features compared to an original set available in CA-Cl*pper. Enabling/disabling some of them allows to keep strict CA-Cl*pper compatibility.

Available features are:

HB_SM_HARBOUR – enables harbour extensions: operators: ++, –, +=, -=, *=, /=, ˆ= objects: assigments to an instance variable

HB_SM_XBASE – enables other Xbase++ dialects extensions: expanding of expresions lists

HB_SM_SHORTCUTS – enables optimized evaluation of logical operators (.and., .or.)

HB_SM_PREPROC – enables preprocessing of commands This is meaningfull if Harbour is compiled with HB_MACRO_STATEMENTS flag

Examples

      INIT PROCEDURE IWANTCLIPPER()
         hb_SetMacro( HB_SM_HARBOUR,  .F. )
         hb_SetMacro( HB_SM_XBASE,  .F. )
         RETURN
