A minor correction to my own e-mail:  VALID is not a command, but
a keyword of the @...SAY...GET command.  That is where it is 
documented in the dBASE IV manuals.  Sorry for this extra bandwidth.

The pattern is roughly:

@ 10,10 SAY "Enter your name: " GET m->namevar VALID Myudf(namevar)

Note that the UDF after VALID must return either .T. or .F.
