What should be my standard choice of integer type in RPGLE?

When I want an integer in an RPGLE program, what data type should I choose? I'm talking about an integer that doesn't correspond to any field in the database, just a normal general purpose integer - kind of the equivalent of an int in Java.

Here's a chart from the ILE RPG Programmer's reference guide:

byte -  3I 0  (1-byte integer)
short-  5I 0  (2-byte integer)
int  - 10I 0  (4-byte integer)
long - 20I 0  (8-byte integer)

I use the 10I 0 form of integer most often. You'll find it's used in most of your API calls as well.

You can use the binary (signed integer) (B) or integer (unsigned integer) (I) types. You can specify the size with the digit values of 3 (1 byte), 5 (2 bytes), 10 (4 bytes) or 20 (8 bytes). The equivalent of a Java int would be 10B.
