Assembler problem....

[RichardL]

This is from a long time jaPBe + PureBasic user... but an absolute new boy with assembler on PC.
(But I wrote assemblers for other processors and know what they are about)

Please excuse posting here as well as in the jaPBe forum... I'm desparate

Simply put, the code snippet works when complied on its own BUT... when I copy and paste it into a larger program using the same jaPBe editor it:

(a) Does not highlight the op-codes
(b) Will not compile (Line 513 - Syntax Error!)
(c) Behaves the same when I copy the whole thing into PB's own editor.

Yes... it is declared in the large program.
Yes... ASM support is enabled.

I must be doing something really stupid; please can anyone suggest what?

Best regards
RichardL

Code: Select all

Declare ToggleWatchDog(TimeOut)

T.l = ToggleWatchDog(6)
Debug T.l

Procedure ToggleWatchDog(TimeOut)
  INC TimeOut
  MOV Eax, TimeOut
  ProcedureReturn 
EndProcedure

Hi Richard,

I just pasted your snippet in several programs, and there is no problem : INC and MOV are highlighted, no compiler error.
Sorry I cannot reproduce the problem (using PB4.20 final).

Can you reproduce the problem from the command line, using PBCOMPILER.EXE directly? If yes, I would suspect a compiler bug.

PS : did you tried like this ?

Code: Select all

Procedure ToggleWatchDog(TimeOut) 
  !INC dword [p.v_TimeOut]
  !MOV Eax, dword [p.v_TimeOut]
  ProcedureReturn 
EndProcedure

So you don't need to enable inline asm.

Hi,
I pasted your suggested code into the main program and I get highlighted code, but when I compile:

INC dword[p.v_Timeout]
error: undefined symbol

On its own (same instance of jaPBe) I get the same message.
Well at least we are getting consistent

I'm using:

jaPBe 3.8.3.697
PB 4.02

Thanks for your interest,
RichardL

Just tried with PB4.02.
I only get an '!INC dword [p.v_TimeOut] : undefined symbol error' if TimeOut is not defined in the code, like

Code: Select all

Procedure ToggleWatchDog(TimesOut) 
  !INC dword [p.v_TimeOut] 
  !MOV Eax, dword [p.v_TimeOut] 
  ProcedureReturn 
EndProcedure

or

Code: Select all

Procedure ToggleWatchDog(Timeout) 
  !INC dword [p.v_TimeOut] 
  !MOV Eax, dword [p.v_TimeOut] 
  ProcedureReturn 
EndProcedure

Maybe some upper/lower case problem ?
But I am no asm guru ...

Your code runs fine here:

Code: Select all

Declare ToggleWatchDog1(TimeOut)
Declare ToggleWatchDog2(TimeOut)

T.l = ToggleWatchDog1(1)
Debug T.l
T.l = ToggleWatchDog1(2)
Debug T.l

Procedure ToggleWatchDog1(TimeOut)
  INC TimeOut
  MOV Eax, TimeOut
  ProcedureReturn
EndProcedure

Procedure ToggleWatchDog2(TimeOut)
  ! INC dword [p.v_TimeOut]
  ! MOV dword Eax, [p.v_TimeOut]
  ProcedureReturn
EndProcedure

As compiler options:

- enable inline support

I don't see a problem...
