Subject: Graphics Question
Errors-To: icon-group-errors@cs.arizona.edu
I have just started using Icon ver 9 for Windows NT and I have a question. I
would like to be able to do 3 things:
. Clear a window
. Go to a cursor position in the window
. Write text to a window
When I try to use GotoXY(x,y) to do the second item, the system responds with
an error:
Run-time error 140
Window expected
Offending value: &null
What did I do wrong? How can I do the above actions?
Thanks in advance for the help.
