Re: Making sense of 4-byte binary fields

Only true if you use the size notation.  If you use positional
notation (e.g. '1  4b 0') then you specify the size as a number of
bytes.  At issue is backward compatibility.  Believe it or not, I
recently compiled a program from System/3 RPG.  It has program
described files using positional notation (obviously).  The main
change was DISK44 to DISK.  The point is that we still have positional
notation for backward compatibility's sake.

IBM _could_ have chosen some different mechanism to represent integers
and then people would be complaining that there are THREE ways to
define a number (position, length and the new one.)

For the original poster, the FAQ has some help in this regard, as well
as a link to an excellent page describing how to convert from C data
types to RPG IV data types by the esteemed Barbara Morris.
