	I have recently been asked to do some maintenance on an 
existing R:BASE system.  While I have a good amount of 
experience with databases in general, my R:BASE experience is 
mostly limited to the EXPRESS programs, and I now find myself 
needing to do some "true" coding in R:BASE.  And I could use 
a little help :^)

	The biggest problem I'm facing right now is the creation 
of a "zoom" list.  That means that when a user enters a field 
on a data entry form, I want to have a list of valid values 
for that field appear.  The problem is that the list of 
valid values is not static (it's a list of building tenants, 
and needs to be updated when people move into the building).  
If it were a static list, I would just use the CHOOSE command and 
have a menu prepared.  But the list of tenants is actually a 
column of data in a table.  Is there an easy way to create a 
menu of this data?  I'm thinking right now of dumping the 
data to an ASCII file, and then using the CHOOSE command on 
it, but that means I need to provided for the maintenance of the 
ASCII file, and I would also need to split up the data, as 
there is too much to put on one CHOOSE menu!

	Has anyone ever done something similar to this?
