  Is there anyway to do Overflow checking for LONGINT's from within pascal
with out having to turn on overflow checking.  I would like to avoid 
overflow checking because it generates a nasty system error, and I just 
want to be "flagged" if the operation overflows.

  Would it be possible to write an Assembly language routine to do this and
then link it into Pascal as a function.  I'm not real up on 68000 assembly.
Any help would be appreciated.  Please e-mail responses.  I'll summarize
the responses if requested.

  Thankyou
