Re[2]: Using API's ?

     If it was late 80's - early 90's, I would imagine it was verion 2 you 
     were using, or at best 3.0.5 (which was a jumped-up version 2 release 
     anyway).  In those days, there was one fairly slim API manual, and IBM 
     were really only getting to grips with openness on the '400 anyway.
     
     My experience in the last couple of years is that the AS/400 APIs are 
     a model of stability, with backward compatibility a very strong 
     priority.

Yes Scott it did happen to me and remember I was not originally using the 
QSYSINC files. I was doing what you were recommending, creating beautiful 
headers of my own. I wish I could remember the exact API but I would imagine 
it was one of the work management API's as that was the sort of thing my 
employer had me working on at that time (Late 80s early 90s). Programs were 
working wonderfully one day and then after we installed a new release BOOM 
all sorts of things started blowing up. I found the common thread of trouble 
and it was all related to one API. I ended up having to compare the QSYSINC 
with my include and low and behold there was a difference (one good enough to 
cause a decimal data error if I remember correctly) Again I am not sure which 
version of the OS it was that caused this problem, but it definitely was a 
source of major grief.
     
Second I never code my API programs in CL. Almost all my programs require 
the use of pointers or iterating over huge lists of things. CL is just way 
too inefficient when it comes to that sort of thing.
     
Sorry that you doubt me... but I guess that is bound to happen sometimes.
     
Sincerely
Eric
