Is it possible to store ASCII value 7 (terminal beep) in a database table? I am accessing a navision database through a terminal and want to let the terminal beep. Any suggestions?

    if you just need the client to beep, then use the following:

    BEEP(Frequency, Duration)

    e.g

    BEEP(300, 100) will beep the sound of 300Hz for 100 Miliseconds(1 Second)

    You get BEEP from
    C/AL symbol Menu -> DIALOG -> Functions -> BEEP

    It is not the client that has to beep, it's the VT100 terminal...

    Can you redefine the ASCII code 7 mapping for the operating system your terminal is connected to, to another printabkle character.

    Hallo,

    try this code in a codeunit: 
    OnRun()
BeepString[1] := 7;
ShellExec('echo '+ BeepString);

SLEEP(3000);

BeepChar := 7;
ShellExec('echo '+ FORMAT(BeepChar));
    and this function in the Codeunit: 
    ShellExec(piExecCommand : Text[250])
SHELL('cmd','/c',piExecCommand);

    with following definitions:
    Name           DataType      Subtype       Length
BeepString     Text                        1
BeepChar       Char
