What's going on is the actual file on disk is huge, but the file length is set to just the opening code. What happens is, slow DOS loads the opening code and runs it; the opening code figures out where it came from and blasts the rest of the file into memory, using the text screen as scratch space for the disk routines. Such loaders are almost definitely Disk ][ or Dos 3.3 specific, and you are not going to be able to get them to work under ProDOS without patching them. Todd Whitesel toddpw @ tybalt.caltech.edu
