RE: API -> Commands

One reason is to allow the use of commands to construct custom interfaces 
without having to write entire programs.  We have a software product that 
has about 150 CL commands that can be used to create custom communication 
interfaces between the 400 and "some other box" (ASCII).  Our clients can 
arrange the commands fairly easily in a CL program without having to know 
anything about the programs that are working behind the scenes.  Some of 
those programs are RPG, some CLP, ASM and C, but all they see are the 
commands and CL.  For this type of application you have many different 
functions and many programs to accomplish them.  You have to have something 
to control the whole process, and on the 400 that's CL.

As I recall from this article, the CL is actually calling an RPG program
to do these functions.

Which makes me wonder...   why not just write the program in RPG to begin
with?  CL isn't any easier to code, it's certainly not as powerful, etc.
