Once a program is cataloged, you no longer need to type the "RUN filename 
programname".  You can just type the programname.

Note that if the program is a subroutine AND it has arguments, you cannot run 
this from TCL.  It will blow up right away.  No harm, but no execution either.

You also have to catalog a program in order to CALL it by another program.

Be sure to understand the impact of cataloging globally (the default) vs. 
locally.  We catalog everything locally on our box which simply builds a VOC 
pointer to the object code.  This means that once it is cataloged once, we 
never need to catalog it again, but other accounts cannot see it w/o being 
cataloged in those other accounts too.  Globally cataloged programs are 
available to anyone on the box (but can lead to confusion between different 
account w/ different versions of the same program).  Both global and local have 
their advantages and disadvantages.

John answered your sentence stack commands, so I'll take a shot at how to 
execute a program.

Typically programs are stored in type 1 files, aka directories or folders, 
(terminology usually depends upon base operating system, *ix or windows).

There's a corresponding file containing the object code.  To execute the 
program, you would typically enter RUN filename programname at the command 

Then, there's cataloged code which is a method of storing object code so that 
it can be referenced by multiple users, (unless it's cataloged "locally").

You can also execute a program directly from its native host without entering 
UniData if you know where the binary executable lives.

The last three are included only for some semblance of completeness, I believe 
that the answer you're looking for right now is paragraphs two and three.
