ASM Community

On the core topic:

// let's assume you have a bunch of functions like
// long ReturnSum(long x,long y); or
// long ReturnMul(long x,long y);

typedef long(*operacia)(long, long);

operacia Operate[]={
ReturnSum,
ReturnMul
};

Then you'll do:
Operate[0](x,y); // for sum
Operate[1](x,y); // for multiplication

long opi,result;
... fill opi with something here
result = Operate(x,y);

if in your code you can't completely control the "opi" variable.. That is if we get opi=2 here, you'll get a GPF. If the operations are not in complete consecutive order, you'll have to make a lookup table to see which case what operation is - which can also be a bit slow unless you do a partition search of the sorted entries. - like in the switch macro posted at this board.

Comments in asm should be in my style :-D :

;----[ parse arguments ]--------------------------\

	.if !pDest

		m2m pDest,FocusedWorkspace

	.endif

	.if !pSrcWorkspace

		m2m pSrcWorkspace,FocusedWorkspace

	.endif

	mov eax,pSrcWorkspace

	cmp eax,pDest

	je _ret ; can't move from one place to the same

	;-------------------------------------------------/

	

	;----[ show or hide windows if necessary ]------------\

	mov eax,pSrcWorkspace

	.if eax==FocusedWorkspace

		foreach pSrcWorkspace,invoke ShowWindow,EDX,SW_HIDE

	.endif

	mov eax,pDest

	.if eax==FocusedWorkspace

		foreach pSrcWorkspace,invoke ShowWindow,EDX,SW_SHOW

	.endif	

	;-----------------------------------------------------/

	

	; delete all windows from pSrc, insert them in pDest 

	foreach pSrcWorkspace,multi icall pSrcWorkspace,ObjVector,delete,EDX | icall pDest,ObjVector,insert,EDX

Block comments are usually an indication that the code can be refactored to smaller functions...
That mostly applies to high level languages, though.
