Manuals

[Lee]

I am looking for a manual that can give a describtion of
how the functions work and also how to use them. Is there
one out there. I am looking for the proper use of an
external function or call.

Look in MSDN for the Programmers Reference ("Office XP Developer's Guide"
for example).

Use help in the VBE for specific functions.
