I an trying to write a macro to replace several PBP statements.
I want to replace this:
Code:
gl_x1 = 30
gl_y1 = 45
gl_x2 = 60
gl_y2 = 45
gosub gl_line
with this:
Code:
@ glcdline(30,45,60,45)
using this macro:
Code:
ASM ; glcdLine '@ GLCD_line x1,y1,x2,y2
#glcdline macro x1,y1,x2,y2
MOVE?WW x1, _gl_x1
MOVE?WW y1, _gl_y1
MOVE?WW x2, _gl_x2
MOVE?WW y2, _gl_y2
L?CALL _gl_line
endm
#define glcdline(x1,y1,x2,y2) #glcdline x1, y1, x2, y2 ; allows paretheses in macro
ENDASM
all vars are words.
The PBP code works giving me a cross centered at x=45 y=45
the macro gives me horizontal and vertical line of full screen size crossing about x=10, y = 10
Thanks
Dave
