Parsing System Built-In Names

When the literal or named constant specified on a bound call starts with "CEE" or an underscore ('_'), the compiler will treat this as a system built-in. (A bound call results with either CALLB or with a prototyped call where EXTPGM is not specfied on the prototype).

If it is not actually a system built-in, then a warning will appear in the listing; you can ignore this warning.

For more information on APIs, see the IBM® i Information Center programming category. To avoid confusion with system provided APIs, you should not name your procedures starting with "CEE".
