- Dear Judy,
-
- Seems to be your lucky day -- two answers for two questions!
- There again, maybe you'd prefer not to have this answer.

- You assume, I fear, in error. There is, in my experience, no reliable way
- of dealing with erros. So much so that I've given up using isql in this
- mode many, many moons ago, and I use my own ESQL/C program instead. Your
- test script doesn't reveal the full extent of the problem:
-
- isql - - <<!
- database aspdb;
- begin work;
- insert into table01 values (1, 2, 3)
- insert onto table02 values (1, "abracadabra", "ambidextrous");
- insert onto table02 values (1, "elementary", "sub-atomic physics");
- commit work;
- !
-
- Since there is a typo (the "onto"), the second and third insert statements
- will fail, but the commit will occur and work! Ouch! If you're really
- interested, I could probably send you the program I use instead.

- PS: I assume $IFXDIR is a local synonym for $INFORMIXDIR? Not that it
- matters.
