So, what's happening (for me) is for a line that's wider than it is higher (or equal), it appears from very initial testing to draw correctly. But if it's higher than it is wider, it doesn't?

Re: Graphical Displays with PBP3
Excellent! Hats off again Richard. This looked like a lot of work in putting it all together. If we ever meet, the drinks will definitely be on me!

Re: Graphical Displays with PBP3
Richard,
Another question: can we pass variables as parameters to these geometric routines?
Like:
DRAWLINE My_x1, My_y1, My_x2, My_y2, 1
So far I'm trying to pass byte size variables but getting illegal opcode messages at compile?

EASY , Just add the needed macro's to the include file, you can dial up whatever you likeAnother question: can we pass variables as parameters to these geometric routines?

Re: Graphical Displays with PBP3
You need a macro likeDRAWLINE My_x1, My_y1, My_x2, My_y2, 1
DRAWLINE?BBBBC
the error message will tell you this does not exist
the existing drawline macros
Code:;LINE DRAWLINE?WWWW macro X0in ,Y0in ,X1in ,Y1in MOVE?WB X0in ,_s_xstart MOVE?WB X1in ,_s_xend MOVE?WB Y0in ,_s_ystart MOVE?WB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?WWBW macro X0in ,Y0in ,X1in ,Y1in MOVE?WB X0in ,_s_xstart MOVE?BB X1in ,_s_xend MOVE?WB Y0in ,_s_ystart MOVE?WB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?WWBB macro X0in ,Y0in ,X1in ,Y1in MOVE?WB X0in ,_s_xstart MOVE?BB X1in ,_s_xend MOVE?WB Y0in ,_s_ystart MOVE?BB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?WWCC macro X0in ,Y0in ,X1in ,Y1in MOVE?WB X0in ,_s_xstart MOVE?CB X1in ,_s_xend MOVE?WB Y0in ,_s_ystart MOVE?CB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?WWWB macro X0in ,Y0in ,X1in ,Y1in MOVE?WB X0in ,_s_xstart MOVE?WB X1in ,_s_xend MOVE?WB Y0in ,_s_ystart MOVE?BB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?BBBB macro X0in ,Y0in ,X1in ,Y1in MOVE?BB X0in ,_s_xstart MOVE?BB X1in ,_s_xend MOVE?BB Y0in ,_s_ystart MOVE?BB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?CCCC macro X0in ,Y0in ,X1in ,Y1in MOVE?CB X0in ,_s_xstart MOVE?CB X1in ,_s_xend MOVE?CB Y0in ,_s_ystart MOVE?CB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?CCCB macro X0in ,Y0in ,X1in ,Y1in MOVE?CB X0in ,_s_xstart MOVE?CB X1in ,_s_xend MOVE?CB Y0in ,_s_ystart MOVE?BB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?CCCW macro X0in ,Y0in ,X1in ,Y1in MOVE?CB X0in ,_s_xstart MOVE?CB X1in ,_s_xend MOVE?CB Y0in ,_s_ystart MOVE?WB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?BBCC macro X0in ,Y0in ,X1in ,Y1in MOVE?BB X0in ,_s_xstart MOVE?CB X1in ,_s_xend MOVE?BB Y0in ,_s_ystart MOVE?CB Y1in ,_s_yend L?CALL _dline endm DRAWLINE?CCCCC macro X0in ,Y0in ,X1in ,Y1in,Col MOVE?CB Col ,_colour MOVE?CB X0in ,_s_xstart MOVE?CB X1in ,_s_xend MOVE?CB Y0in ,_s_ystart MOVE?CB Y1in ,_s_yend L?CALL _dline endm
you could add this
Code:DRAWLINE?BBBBC macro X0in ,Y0in ,X1in ,Y1in,Col MOVE?BB X0in ,_s_xstart MOVE?BB X1in ,_s_xend MOVE?BB Y0in ,_s_ystart MOVE?BB Y1in ,_s_yend MOVE?CB Col ,_colour L?CALL _dline endm
or set the colour manually
eg colour=1
and use
DRAWLINE My_x1, My_y1, My_x2, My_y2
which already exists
DRAWLINE?BBBB
with a mono display you probably wont change the colour too often
