SET BELL TO
[<frequency expN>, <duration expN>]

<frequency expN>

The frequency of the bell tone in cycles per second, which must be an integer from 37 to 32,767, inclusive.

<duration expN>

The duration of the bell tone in milliseconds, which must be an integer from 1 to 2000 (two seconds), inclusive.

Description

When SET BELL is ON, dBASE Plus produces a tone when you fill a data entry field or enter invalid data. SET BELL TO determines the frequency and duration of this tone, unless the computer is running Windows 95 and has a sound card. In that case, the Windows Default sound is played (through the sound card) instead of the tone.

Displaying CHR(7) in the results pane of the Command window sounds the "bell" whether SET BELL is ON or OFF.

SET BELL TO with no arguments sets the frequency and duration to the default values of 512 Hertz (cycles per second) for 50 milliseconds.
