Description
The size of the full screen buffer in bytes
The full screen buffer contains menu, screen, and image definitions and the values of screen variables and image data blocks. If multiple screens, menus, or blocks are defined in a request, Model 204 reuses the full screen buffer as it processes each screen, menu, or block.
LFSCB must be large enough to hold the largest screen, menu, or image definition in a request. Set it no lower than 1932 unless you set it to zero, indicating that the full screen feature is not used. For full screen use on 3270 terminals, LFSCB normally should be set to 5000. It must not exceed 65528.
For an application subsystem user, LFSCB must have a minimum value of 256.
