I'm currently converting some real mode code over to GASP/DJGPP, and I'm
having some problems. Some of the code I want to convert is
self-modifying, and I'm not having much success with it. I believe that
what I need to do is use a selector which points to the code section but
allows read/write access, but I haven't been able to set this up. There
appears to be no documentation on the selectors used by GO32.

So, what I need to know is: what selectors are set up by GO32, and can I
use/modify them to allow self-modifying code? If so, how? :).

Thanks in advance for any help.
