The IBM conversion does not change arithmetic operations to EVAL for just
this reason.  It is the third party converters that change the code, and
thus the logic.  EVAL is NOT the equivalent of ADD, that's clear enough!

I frankly would have liked to have seen a different option on the error
message; "allow truncation."  Many old school programmers like myself easily
forget about the different rules when working with eval, especially
precision of intermediate results.  But I must say, having a hard error at
runtime has saved my bacon.  Rather than invisibly corrupt the database, at
least I get to hear about the problem before it's been propagated into next
quarter...  Yes, it's a pain to interrupt a long running job and have to
re-do it, but it's better than poisoning the database.

Just my two cents
