Ah - as in fiscalYr could be -9999, so it needs 5 digits to get -10000?

This is part and parcel of the 'expression' rules for EVAL.
Basically, 'fiscalYr - 1' is an expression.  In order to hold all the
possible digits of the resulting value, the compiler applies some rules to
create an 'intermediate' or 'work' variable.  The %editc() is working
against the work variable.

I don't have the manual reference handy, but it's in the section on numeric
precision in the RPG Reference.
