Good catch.  Several things happen in the main program, where `var' is 
defined, before -regse- ever gets called.  And, -regse- doesn't refer to 
`var' until it gets to the -outreg- command.

When programs get complicated it is easy to get mixed up on these sorts of 
things.  Again, occasionally tossing in a -macro dir- or -set trace on- 
command can help you to see whether the program is doing what you think it 
should be doing.
