Rob,

I had used alias in a Foxpro 2.5 application once. The requirement was a multi-user application for a bank book to be maintained in such a way that each user use one bankbook at a time and there were 3 users sharing 4 bankbooks among them. What I did was this - whenever a bankbook was created, I made a file like BKT01.dbf, the next would be BKT02.dbf & so on. Whenever any user selected a bankbook, I would use a command like
USE BKT01 alias BANKTR
or
USE BKT02 alias BANKTR

Then I would use BANKTR in my select(SQL) statement. This way I could allow creation of upto 99 bankbooks and use the same code all the time because of the alias.

I haven't converted the application to VFP yet.
