RE: The target for a numeric operation is too small!!!!!

For one thing, the truncate numeric does not apply to values in
expressions(which is what an eval is), overflow within expressions always
generate an error(this is from the help on the parameter).  Secondly, why do
you want your report to have an invalid value versus getting an error?  Your
report field should be large enough to hold any value expected.  If you want
your report field smaller then you should check the value in your program
and print some indication on the report that the value overflowed (like
********* or something).  I have seen too many problems caused by reports
having incorrect numbers due to overflow and truncation.  You should be glad
the program halted and did not complete with incorrect data as if nothing
was wrong.  I recommend changing the program to handle the overflow.
