Exsqueeze me?!?  Where in Carl's sample program did he use floating
point numeric variables?  He was using decimal numeric variables
exclusively.

BTW, you don't really expect 30 digits of precision from floating
point variables, do you?  I agree with you - until you understand
the difference between the floating point and decimal numeric types,
please don't use floating point.  (Study Chapter 10 of the ILE RPG
Reference manual.)
