Description

The ON READERROR command executes the specific <command> when a data entry error is made. Data entry errors are: invalid dates, number out of range, failed VALID condition. ON READERROR can be used to replace the default error messages that are given when these errors occur. If no <command> is specified with the ON READERROR command, any previously issued ON READERROR setting is cancelled.


Example

procedure readtrap
dialog box "Date is out of range"
return
 
dToday = date()
on readerror do readtrap
@10,00 say "Enter Date" get dToday;
range {01/01/2000},{01/01/2005}
read
on readerror
