That is the easiest method to use when using real card images too.
BSAVE a deck of card image files(with RGB colors all set the same or to default) and name them "Card1.bsv" etc. Then when you want to display them, the program can BLOAD and PUT the images.
BLOAD "Card" + LTRIM$(STR$(cardnum%)) + ".bsv" etc.
Goto: Qbasic Station .com (no spaces in link) and look for Member Files/Needs Help. I made a Texas Holdem game that has no betting yet because of the difficult table rules in TexHold.
I also have a set of cards that "TheBob" made included (default colors).
If you need help, let either of us know!
