Graphical Displays with PBP3

it appears there was a bug in drawing vertical lines. this now works

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!

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 like

DRAWLINE My_x1, My_y1, My_x2, My_y2, 1

You need a macro like
DRAWLINE?BBBBC
the error message will tell you this does not exist

the existing drawline macros

;LINE 
DRAWLINE?WWWW  macro X0in ,Y0in ,X1in ,Y1in
    MOVE?WB    X0in ,_s_xstart

    MOVE?CB  Y0in ,_s_ystart
    MOVE?CB  Y1in ,_s_yend
    L?CALL   _dline 
  endm

you could add this

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

a 5 input user command has the potential to need 5 raised to the 7th power of macros to cover every input permutation possible
a ridiculous number, i only ever create what seems useful to me. it's trivially easy to add any other combination you app calls for
and the compiler error virtually spells it out for you
