In article <8905181714.AA08425@postgres.Berkeley.EDU> dillon@POSTGRES.BERKELEY.EDU (Matt Dillon) writes: Now, unfortunately, you can't ro-page the text (code) segment directly from an Amiga executable due to the relocation information [...] I don't see that that necessarily holds. Isn't the relocation information just a list of the points in the file where you need to add the base address where loaded? I don't see why you couldn't have the MMU map the memory to start at 0 [as far as the program/processor is concerned] and ignore the relocation information entirely. Now, you might have trouble getting something of the sort to cooperate with the operating system, as Exec/AmigaDOS tend to assume everything is in a single large address space, but I don't see that it necessarily CAN'T be done. Let it be a challenge. :-) Deven -- shadow@[128.113.10.2] <shadow@pawl.rpi.edu> Deven T.
