The obvious way to share code is to make a separate > process out of that code. ld -n and -i format code IS shared. I think what he is after is shared libraries. Even though shared text segments occurs in most UNICES, many programs contain a substantial number of library routines that are common to programs that are not loaded from the same disk file. Other operating systems have provision to keep library routines in memory so only one copy exists even though their may be many different programs using them. -Ron
