PBP 2.6C assembler

ok, nope i'm lost again...

The macro for CMPGT?WCL is...

CMPGT?WCL macro Win, Cin, Label
    if ((Cin) < 0)
        L?GOTO  Label
    else
      if ((Cin) < 0ffffh)
        MOVE?WW Win, R0
        MOVE?CB (Cin) >> 8, R1 + 1
        MOVE?CA low (Cin)
        L?CALL  CMPGT
        BIT?GOTO 0, STATUS, Z, Label
      endif
    endif
    endm

So what is MOVE?WW, MOVE?CB and MOVE?CA oh and L?CALL and BIT?GOTO... Like... seriously!

Total guess; math calculations in IF?

Hi,

o what is MOVE?WW, MOVE?CB and MOVE?CA oh and L?CALL and BIT?GOTO... Like... seriously!

They are more macros, move word to word, move constant to byte and so on. You should be able to find the actual code that those macros consists of at the same place you found the code for "top level" CMPGT?WCL macro.

Henrik, i already looked... It's not in the MAC file...
It looks like it's embedded into PBP... which is not helpful...

They are in the .lib file for the device family you're targeting, from pbppic14.lib for example:

;****************************************************************
;* MOVE?WW    : Macro - Move WORD variable into WORD variable   *
;*                                                              *
;* Input      : Win = WORD variable                             *
;* Output     : Wout = WORD variable                            *
;*                                                              *
;* Notes      :                                                 *
;****************************************************************

MOVE?WW macro Win, Wout
        MOVE?BB Win, Wout
        MOVE?BB (Win) + 1, (Wout) + 1
    endm

Hope that's helpful....

Thats wonderful... I think that's everything i was missing...

However why does the pic18 lib and macro's have bank checking routines when, according to the data-sheet the ram and program memory maps are laid out in a linear sequential manner and not in banks?
Unless i'm missing something?
