Re: SYNC vs LINK

Micheal:

Yes, as I recall, SYNC (SVC 12) was designed to invoke exit routines on behalf of system routines (like OPEN, CLOSE, etc.), and therefore calls on the program by its address (found in some exit list or exit pointer), whereas LINK (SVC 6) calls out a program by name (as Binyamin says) and was intended for calling separately compiled program subroutines, which would have a CDE (either created by the LOAD or LINK SVC routine).

Does that mean sync doesn't have to be associated with a CDE

SYNC is to address. LINK is to name.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
