This variable affects DOS and Windows networks with multiple-user licenses.
If A_WAIT_FOR_LICENSE is set to "1" (on, true, yes), the runtime waits until the number of
users on the network has been counted before executing the COBOL application.
If the counting procedure determines that the user limit has been exceeded, the
application is not executed.
A value of "0" (off, false, no) causes the application to begin running in
parallel with the user counting procedure. If the user limit has been exceeded,
the application is stopped at the next ACCEPT statement.
The default value is "0".
