* source/vm/macro.c
   * source/vm/hvm.c
     % Simplified logic for suppoting macro lists. Removed global variables:
          int hb_vm_iFunCalls = 0, *hb_vm_aiMacroListParameters = NULL, hb_vm_iMacroListAllocated
       which are no longer needed. No longer using any logic in any PCODE case, other than HB_P_PUSHMACROARG.
       No longer using any arrays, or memory allocations.

   * include/hbexpra.c
   * include/hbexprb.c
     * HB_P_PUSHMACROARG will now be followed with a push symbol sequence, indicating its parrent function call.

   * include/hbpcode.h
     * Added decimal values into the description comments for readability.
