The only mention I can find in he code of anything that looks like %gr, %og or %gw is the following statement:

I = WINIO@('%pv%^gr[black,user_resize]&',IWIDTH,IHIGHT,RESIZE)

Catherine,

Clutching at straws:

I'm puzzled by your %gr, as with user_resize and the ^ qualifier you need a callback function, and I could see that was the integer function RESIZE, but then where is the user_supplied graphics handle?

Here's the equivalent from one of my programs (predating the RGB colours default)

I was just about to try a modification in line with that suggesred above. However, before doing this. I re-linked one of my programss and I am back to glorious techniclour! A second program likewise.

I have had no clour for almost 6 months. During that timeI have continued to modify, compile. link and run the codes almost daily. (None of my changes have involved the graphics routines which have been unchanged for many years). This morning things have returned to normal as suddenly as they went wrong. It must be because it is my birthday.

Many Happy Returns, Catherine, but the fact remains that you need an extra parameter to the format code, so maybe it will work, maybe it won't, as it is.

Thanks Eddie.

I will amend the line to

I = WINIO@('%pv%^gr[black,rgb_colours,user_resize]&',IWIDTH,IHIGHT,RESIZE)

I added rgb_colours to the statement as above. The graphs all went back to blue on black - the previous 'no colour' problem.
I took rgb_colours out again and the colour returned.
So, not quite sorted yet ...

I have replaced rgb_colours by vga_colurs and have the colours back again.
I Do you think this may be the solution?

Catherine,

You have probably hit it on the head. John_Silver suggested this, and I dismissed it because I thought that you'd tried it.

But you still haven't got the user-supplied handle for your graphics area, which goes between the callback and the sizes.

Paul may wish to comment that the user-supplied handle is optional if you only have one graphics area, but I certainly didn't get that from reading the documentation, although I would have thought there would be a runtime error. You certainly will struggle without a handle (even if Clearwin+ lets you get away with it) if you want to have more than one %gr.

Eddie,

That is where I have put the vga_colurs, following your advice.
I now have

I = WINIO@('%pv%^gr[black,vga_colours,user_resize]&
& ',IWIDTH,IHIGHT,RESIZE)

So I first tried rgb_colours, as you suggested. When this didn't work I changed it to vga_colours.

Catherine.

Catherine, taking your code, I think it should look like this:
