Re: using toupper()


There's also "3 = char = 1 byte", which was introduced at the same time as
the 20 digit one.

and the 20-digit one is not the same as the C "long" data type, int & long
are the same size.   The RPG "20I 0" is equivalent to the C "long long"
integer.

I suspect that on V4R1, they only had "10I 0, 10U 0, 5I 0 and 5U 0"
