The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
AS/400 and all compatible systems (i5. system i, i series, and others I
don't remember the names exactly) are passing parms by reference. Caller and
callee are using the same storage, defined in the caller. If the declaration
of the parms does not match exactly in type and length, unpredictable
results may occur. Calling a programm from the commandline, or passing
literals, the operating system has to make some assumptions about the
declaration of the passed values, as there are:
- all numeric literals are treated as packed decimal 15, 5
- all other literals are treated as char(32) minimum or with it's length.
Using a user defined command for the caller, the exact matching declaration
could be defined in the command and the operating system does all needed
casting.
