Excerpts from netnews.comp.os.os2.misc: 29-Sep-92 How to debug in OS/2 with G.. by Wey Jing HO@monu6.cc.mon > 1) declare unsigned char **variable; > 2) variable = (unsigned char **)malloc(512*sizeof(unsigned char)); > 3) check malloc if == NULL; > 4) variable[i] = (unsigned char *)malloc(512*sizeof(unsigned char)); > for (i=0; i<512; i++); (sorry, this line should appear first) > 5) check malloc if == NULL; > 6) variable[row][col] = (unsigned char)fgetc(instream); Maybe you mistyped line numeber 2, maybe its wrong. I think it should read: variable = (unsigned char**)malloc(512*sizeof(unsigned char*)); note the sizeof(unsigned char*) part. That's crucial. If what you have typed is what you compile, I'm amazed that it ever worked, even under DOS. Steve "If 'goodbye' were only a word, maybe I'd say it more often." -Stephen Lacy
