I have been having problems with a graphics program on my Apple //e which uses a shape table. The program's length is such that it spills into the region of memory for HGR graphics, causing lines to appear that shouldn't be there (also erasing the last portion of the program). The shape tables are stored in the HGR2 region of memory (which resides just above the HGR region). How can I, through machine language, basic, or whatever, move the starting point of the free memory above these graphics pages. This would be a godsend in freeing up enough memory to get my program back on it's feet. HELP! HELP!...please. vlf "babyface"

Hope this helps. Lee Heins /
