Class

Screen Forms


Purpose

Specify the value to be entered in a field on a form


Syntax

SET FIELDVAL TO <expC>


See Also

@...GET, SET VALIDATE


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
