An internal CLI variable, CliUsrLgnOn, controls the CLI User Logon Exit function.


This variable is initialized to TRUE in CLI at startup. Setting the value to FALSE turns off the user exit logon function, that is, if set to FALSE, CLI will not call CliUsrLgnExt.

CliUsrLgnOn is a global variable. To enable the CliUsrLgnExt() function, set this variable to TRUE in CliLgnEx.c. By default, CliUsrLgnOn is FALSE.
