Purpose
Enable or disable the terminal bell inside forms
Syntax
SET BELL ON | OFF | (<expL>)
See Also
@...GET, CHR(), SET CONFIRM, TONE()
Description
If SET BELL is ON then the terminal bell will sound if an attempt is made to enter invalid data (e.g. alphabetic character in a numeric field), or enter more characters into a field than it can contain when SET CONFIRM is ON. This command allows the optional logical expression <expL> to be evaluated. If a value of .T. is returned, BELL is set ON. If a value of .F. is returned, BELL is set OFF. Note that <expL> should be enclosed in round brackets. By default, BELL is ON.
