Defines the sequence of characters, or the function or attention key or lightpen, which causes IBM Session Manager to transfer control backwards through the active applications for a Menu panel.
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 escape, which must be delimited by a null or a space when issued, can be from one to eight characters long, PF1-PF24, PA1-3, ATTN, CLEAR or PEN.
By defining the Menu panel appropriately, using a defined input field (variable t_bwd) the escape sequence can be modified dynamically. See the PANEL statement in the Panels, Scripts and Variables manual.
