It is in the Files area of the LBB Yahoo group, but it's called LBLIB.BBCC (note the unusual extension):
https://groups.yahoo.com/neo/groups/lbb/files
But since it's a 'crunched' library it's hard to read and I wouldn't necessarily have expected you to look at it. I probably should have drawn your attention to the fact that you would need to use @memhdc% as the 'destination' DC. It's the old problem of not knowing what you don't know!

Not in that particular program, no; if you were to trace through PROC_dim1d$ you would find that in fact it just does a conventional DIM.
The issue arises if a program DIMs (or REDIMs; in LB they are synonymous) that same array again. In BBC BASIC that would simply give rise to a 'Bad DIM' error so the procedure in LBLIB checks to see if the array was previously defined and if so avoids generating the error.

Indeed, I often don't know what I don't know!
Thanks again for the help. Now to update the full version of my program to work with StretchBlt...

I've tried finding LBLIB.BBCC in the files area and I can't find it either. It might be a mystery to me, but I'd like to have a look at it.

I'm mystified by that. I just clicked on the link I published in my earlier reply, and there was LBLIB.bbcc as the very first file listed!
Of course you'll need to be a member of that group before you can see the contents of its Files area; is it possible you neglected to join the group before looking there?

Hi Richard
I've gone back to the link and it does say that I have to be a member to access the LBB area. I can get into the BB4W files area. Do I need to have a separate membership for the LBB area? If so, how do I go about it?
Regards
Ray

It's not an "LBB area", it's a completely different Yahoo group! You must join, just as you needed to join the BB4W group before you could access the files there. I don't know exactly what the process is, subsequent to the introduction of the awful Neo interface, but it should hopefully be obvious.
Richard.

Thanks, I've found out how to join and I've submitted my application for membership to the LBB group. Awaiting a response.
Regards

For those who may be using LBLIB, or may have downloaded it just for interest, please note that it has been updated to version 2.86:
https://groups.yahoo.com/neo/groups/lbb/files
You must be a member of that group to access its Files area.
Richard.
