In QDOS/SMSQ/E the 'AT' keyword allows the print statement an
imaginary y/x character cursor location to be used. Is there away
of knowing where this is as a function?
for example:
10 AT 10,20 PRINT "FRED";
20 PRINT LOCX : remark this would return 24
30 PRINT LOCY: remark this would return 20
10 AT 10,20 PRINT "FRED"
20 PRINT LOCX : remark this would return 1 (or 0)
30 PRINT LOCY: remark this would return 11
I don't know of any extensions which contain functions like LOCX and
LOCY. The trap #3 call SD_CHENQ returns the cursor position in
characters. It would therefore be easy to produce the keywords LOCX
and LOCY.

I had a quick look through my SBASIC/SuperBASIC Reference Manual and
can't find anything.
I am sure I wrote a small function (CURSOR_POSX and CURSOR_POSY) to
get at these values but which program I used it in, I can't think for
the life of me!.
Of course, there is an easier way...
Use the CHANS toolkit from DIY toolkit (volume C) and then use
PRINT CHAN_W%(#3,34) to grab the x position on channel #3
PRINT CHAN_W%(#3,36) to grab the y position on channel #3
Or try
PRINT CHAN_W%(#ch; 82): rem SD_XPOS
PRINT CHAN_W%(#ch; 84): rem SD_YPOS
for position in cursor coordinates, which is what I think you want.
It may be possible to do this without a toolkit by using the extended
PEEK commands found in SMSQ/E and Minerva. I havnt tried, though.
