This parameter specifies the time interval associated with 'double escape' processing (see 'Double escape' processing).
This common end-user parameter is applicable to these control statements: SYSTEM (see SYSTEM statement), PROFILE (see PROFILE statement), USER (see USER statement), and TERMINAL (see TERMINAL statement).
The time interval is specified in milliseconds. For example, DOUBLESC 100 specifies 100 milliseconds (0.1 seconds). A value of 0 (the default) disables this facility.
The SME command (see the Technical Reference manual) sends the Menu escape key (or sequence) to the last active session.
