The CEExxxxx API's are in this book:
http://publib.boulder.ibm.com:80/cgi-bin/bookmgr/BOOKS/QBJAMM00/CCONTENTS

One of the nice things about the "CEE" API's is that they're automatically
bound to your program, you don't have to explicitly bind them on the
CRTPGM command.

You will have to use CALLB or CALLP, since they are bound -- but this
shouldn't be very difficult -- CALLB has the exact same syntax as CALL,

I'd strongly recommend that you start playing with / learning CALLP,
however, as prototypes are extremely powerful and useful.  :)

Since an RPG example might be hard to find, I'll give you this one:

D Msg             PR                  ExtProc('CEEMOUT') opdesc
D   String                      50A   const
D   dest                        10I 0 const
c                   callp     Msg('Nothing better to say than this?':1)
c                   eval      *inlr = *On

An API is nothing more than a program or service program that has been
written to perform a specific function.  You're doing nothing more than 
calling it. 

Unfortunately, this means every API is different, everything has a
different set of quirks.  If you look in the online books, and search
for titles containing "API", you'll find a bunch of books.   They'll 
give you the specifics... the rest you'll want to learn from
experimentation and from help on this list :)

Good Luck!
