Truncated intermediate results
Whenever the number of digits in an intermediate result exceeds 30 in compatibility mode or 31 in extended mode, the compiler truncates to 30 (compatibility mode) or 31 (extended mode) digits and issues a warning. If truncation occurs at run time, a message is issued and the program continues running.
If you want to avoid the truncation of intermediate results that
can occur in fixed-point calculations, use floating-point operands
(COMP-1 or COMP-2) instead.
