Re: Easy way to get LPAR from RPG?

Funny, I was just working on that this week. I am still in the process of
converting some old code I found on the net (still using B data type and
need to convert it to I). See my code below:

h dftactgrp(*no) actgrp(*caller)

d returndata s 2560
d datalength s 4b 0 inz(2560)
...
c call 'QWCRSSTS'
c parm returndata
c parm datalength
...

Eek!

Quick, change the 4b to 10i (or even 9b). This isn't just a matter of the slight badness of B vs I. This is just plain wrong; 4B is a 2-byte binary and the API needs a 4-byte binary. The API will think the datalength parameter is 167772160 or more (depending on what the 2 bytes after datalength happen to contain).
