Graphics calls don't work (?)

[WSinc]

I tried doing this to open a program -:

type

(windowconfig)wc

status=getwindowconfig(wc)

print *,"window size=",wc.numxpixels,wc.numypixels print *,wc.title OPEN(UNIT = 10, FILE = 'USER', TITLE = 'Child Window 1') OPEN(UNIT = 11, FILE = 'USER', TITLE = 'Child Window 2')

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

and I get a fatal run-time error when it tries to open Unit 10 or Unit 11.

Is there something else I have to do first? The documentation doesn't give me a clue.

How does it know if the UNIT number is pointing to a file on disk or to a window?

[WSinc]

In fact, it mentions "Fatal error when opening FILE." So obviously it's confused about the difference between a graphics window and a disk file.

Make sure you have created a QuickWin project, and USE all the correct modules.

It definitely is a Quickwin Project, and I put USE IFQWIN in the header of the program.

The error message says "fatal error accessing file, unit 10."

Unfortunatety, I could NOT copy and paste the actual error message verbatim.

Can you come up with a small but complete example that demonstrates the problem?

OK, will do. Separate thread.
