How do I aviod this, and what exactly is a > segmentation error? A segmentation violation means that you tried to access memory that you're not allowed to access under protected mode. This would occur if you're dereferencing a NULL pointer, or attempting to access video memory at 0xA0000. Please download and read the DJGPP Frequently Asked Questions list (v2/faq210b.zip from SimTel), and read chapters 6, 8, and particularly 10. It would also be nice if you would post some sample code along with the commands you use to compile it and a copy of the symified crash traceback. hth -- --------------------------------------------------------------------- | John M.
