Hello, I'm having problems setting conditional assembly symbols in the invocation line of A51. The lst file below should have all the details. Thanks
A51 MACRO ASSEMBLER FACTORY 06/30/2004 08:59:58 PAGE 1 MACRO ASSEMBLER A51 V7.01 NO OBJECT MODULE REQUESTED ASSEMBLER INVOKED BY: c:\work\keil\c51\bin\A51.EXE factory.a51 SET(HELPME=1) LOC OBJ LINE SOURCE 1 FACTORY SEGMENT CODE ---- 2 RSEG FACTORY 3 public fixed_presets 4 5 IF (HELPME=1) *** _________________________________^ *** __________________________________^ *** ERROR #A21 IN 5 (factory.a51, LINE 5): EXPRESSION WITH FORWARD REFERENCE NOT PERMITTED *** ERROR #A45 IN 5 (factory.a51, LINE 5): UNDEFINED SYMBOL (PASS-2)
EXPRESSION WITH FORWARD REFERENCE NOT PERMITTED should tell you. the definition of a conditional must exist before the use in an if Erik
You must use $IF and $ELIF directives for symbols you define using $SET and $RESET. The IF and ELIF statements only work on EQU, LIT, and SET statement (which is different from the command-line $SET). Jon
Thanks Jon. Correct and to the point! And Eric, the symbol is defined in the invocation.
