Re: howto make system calls (newbie question)

Well, if it were an optional annex, then it wouldn't be 
mandatorially present, but optional, as garbage collection is 
now.  (That may be a good argument against it, considering the 
status of garbage collection, however...)

Do you mean that all of your users are restricted to batch 
compile/execution cycles?  Then slave sysin to the card reader 
and sysout to the line printer (Unit5 and Unit6, I think they 
were called.)

No.  But perhaps a higher level description could be.  It might 
not have the total functionality of low-level system calls, but 
one often doesn't need that. (I have only used VMS twice, so 
forgive me if I don't know what an ACE is.)

Posix-standard interfaces are good.  That way at least one 
implementation has already been done, so it doesn't need to be 
redone.  It could be swallowed whole into an annex as a proposed 
implementation (licensing issues permitting).
