Specifying input parameters Forms control buffer (FCB) and vertical format control processing The 3211 and 4245 forms control buffer (FCB) defines channel positions and forms length. You may restrict the forms control buffer information by accepting or suppressing the normal processing of host transmitted FCB input. To suppress processing of FCB input, specify FCB=IGNORE in the LINE command. The vertical format unit (VFU) in the JSL and the FCB sent from the host interact as follows: • When you start a job, the VFU table and its associated Bottom of Form (BOF) in the JDE become active. • If no VFU is specified in the JDE, the last FCB sent from the host becomes active. • When a DJDE is used to change a channel assignment, any previous assignments to the channel being changed are suspended until the end of report. At the end of report, DJDE changes are discarded and the last active FCB or VFU becomes active again. • When operating system software is reinstalled or upgraded, the FCB saved on disk is reinitialized to the length of 66 lines with the following channel assignments: Table 2-1. Default channel assignments made at installation Channel Line 1 2 3 4 4 10 16 22 5 6 7 28 34 40 8 9 10 46 52 58 11 12 64 66 The default corresponds to the STD2 default supplied by IBM. • If a Print and Skip to Channel command is sent for an undefined channel, the system executes a Print and Space 1 command. Print position indexing (non-U.S. markets only) The print position indexing (PPI) byte determines whether lines should be shifted horizontally. If either the sixth bit or the seventh bit of the first byte in the loaded FCB is on, the byte is a PPI byte, and the lower five bits indicate the amount of shift. For example, if the first byte is 0 x 48 (01001000), each line shifts seven (0x48^0x1f -1) character spaces to the right (the sixth bit indicates that the shift is to the right).
