That was /exactly/ my concern when I asked "how did you do that". As far
as I know, in the
"classic" PE a ptr read in a background window will just block.
With QPTR, this works (on QPC & SMSQmulator) even when bgio is switched
off:
100 OPEN_NEW#0,"con"
110 WINDOW#0,0,0,0,0
120 OUTLN#0,0,0,0,0
130 REPeat lp%
140 term%=48
150 RPTR #0,xabs%,yabs%,term%,swnum%,xrel%,yrel%,bt$
170 IF yabs%>SCR_YLIM-50:BEEP 7000,10
180 PAUSE 150
190 END REPeat lp%

Great! Thanks. (For anyone wanting info about the RPTR parameters it's on
page 38 of my QPTR ref guide)
While tinkering with the Easyptr equivalent, I think I may have found a bug
in Easyptr's RDPT command:
RDPT #chan%,tvec%,xpos%,ypos%
Should return the absolute pointer coordinate in xpos% and ypos% if passed
positive. It does indeed if pointer position changes for xpos%, but not for
ypos%, which always keeps the calling value.
ptrmenr_cde 4.09 - just to give Marcel a migraine ;-)
Easily worked around by using DIM pr%(15) : PVAL #chan%,pr% : ypos% =
pr%(15)
(always assuming it's not a bug in the first place and just me being totally
stupid as usual).
