Sample code if you want to play around:
Code: (Select All)
screen _newimage(200, 200, 12)
xf = 150
yf = 150
do
x = int(rnd*200)
y = int(rnd*200)
draw "B M" + str$(x) + "," + str$(y)
draw "d15 r15 u15 l15 m " + str$(xf) + "," + str$(yf)
_display
_delay 1.25

Ok, one more shot at this
This seems to work
Screen 9
PSet (10, 10), 2
Draw "D50"
Draw "r100"
Draw "u50"
Draw "l100"
Draw "M25,50"
Draw "M" + "25,-10"
At least it doesn't error out

draw "d15 r15 u15 l15 m " + str$(xf) + "," + str$(yf)
_display
_delay 1.25
loop
And now, for the giggles, try the same program with a little tweak so that the second M command is a relative coordinate instead of a fixed coordinate:
Code: (Select All)
screen _newimage(200, 200, 12)
xf = 150
yf = 150
do
x = int(rnd*200)
y = int(rnd*200)
draw "B M" + str$(x) + "," + str$(y)
draw "d15 r15 u15 l15 m -" + str$(xf) + ",-" + str$(yf)
_display
_delay 1.25

Thanks Charlie and Dimster. It's much clearer now. Time to go play!
The question was related to a little exercise I'm doing at the moment, involving pi.
(no, Bplus, not that pie)!

I hope it's apple! :-))

Does Apple Pi run on Windows?

The plus sign needs to be inside the quoted string like:
Code: (Select All)
Draw "M+25,-10"so the processor knows it's a relative draw. You wouldn't be able to change the plus to minus in that line of code of yours because it would give out a syntax error.

I tried putting Lemonade on my Windows, once, but my keyboard shorted out. I guess I made a pour choice.
