 Subj: CODE & PROC 3.2+              Status: PUBLIC MESSAGE
 Conf: FORTH (58)                 Read Type: GENERAL (+)

      I'm attempting to figure out some of the details involved with
 3.2 +  assembler codeing using CODE and PROC statements.  All I seem
 to be able to do so far is to lock up my PC.  I've used 3.1 assembler
 previously but only for short task CODE statements with all data on
 the stack and available to the CODE procedure.  I could use some
 pointers on two things in the 3.2+ assembler.
     First:  Calling PROC
 .
       PROC +TEST
         AX, # 0001 ADD
         BX, # 0000 ADC
         RETF
       END-PROC
 .
        VARIABLE TEST+  +TEST TEST+ !
 .
       CODE ++TEST
          AX POP BX POP
          TEST+ CALLFI
          BX PUSH AX PUSH
          NEXT,
       END-CODE
 .
     This is my basic trial code in which I have been using as described
 in a comment form 9-12-89 in using CALLFI and RETF via a variable.  Is
 there something majorly wrong or is there some syntax incorrect.
 Debugging is impossible when all variations on a theme lock up the PC.
 .
     The other thing is VARIABLE access via the CODE statements.
 Examples that I have also seem to access strange locations.  Any help
 would be greatly appreciated.
