SET FIELDVAL TO <expC>

Description
The SET FIELDVAL TO <expC> command allows modification of a field value that is being validated from data entered into a form. This command should be used in conjunction with the @...GET VALIDATE WITH command. If the VALIDATE WITH option is used on non-character variables, SET FIELDVAL TO can still be used, because the <expC> is automatically converted to the data type of the calling variable.
Example
procedure check_event parameters data if empty(data) set fieldval to "BALLET" endif set validate on return @10,0 say "Event " get event validate with check_event read
