... could be a nice thing to make code easier to read. (especially for INLINE snippets)

Code (glbasic) Select


MACRO newcommand(var)
    INLINE
        var++;
        ...
    ENDINLINE
ENDMACRO


// use in GLBasic code
LOCAL counter%
newcommand(counter)

FUNCTION can do the same...

EDIT:

Code (glbasic) Select

LOCAL my_var = 10
Add(my_var) 

WHILE TRUE 

	PRINT my_var,10,10

SHOWSCREEN
WEND
END



FUNCTION Add: BYREF var
INLINE
	var++;
ENDINLINE
ENDFUNCTION

sure, but FUNCTION always does have overhead (calling, stack, ...)
Macro is a simple replacement of code, so produces bigger, but faster code.

macros are not type safe. I would have to run a pre-pre-compiler for the macros. A nice idea, though.

What about platform specific macros? That way you could do something like

if for iphone
resolution = 100x200
else
resolution = 800x600
endif
