RE: Open Source RPG

[Colin Williams <Williamsc@xxxxxxxxxxxxxxxxx>]

Take from the System API Reference 1.2.2.3

 "For API BINARY(4) fields, RPG developers should use 
either positional notation or a length of 5 to 9 in order to allocate 
a 4-byte binary field"

It makes no mention of 4 byte integer fields, does this mean all my 9B 0
definitions have a potential error
Even some of the API data structures in QSYSINC use 9B 0.
