FCB Images in SYS1.IMAGELIB

Two standard FCB images, STD1 and STD2, are included in SYS1.IMAGELIB during system installation. The names of these standard images begin with the characters “FCB2”. You can define FCB images whose names begin with “FCB4” for the 4248, 3262 Model 5, and 6262 Model 14 Printers. These printers can use both the “FCB2”-prefixed images (referred to as 3211 format FCBs) and the “FCB4”-prefixed images. All other printers, except the 3800, can use only “FCB2”-prefixed images.

This section describes how you can create or replace “FCB2”-prefixed images. z/OS DFSMSdfp Utilities describes how you can use the IEBIMAGE utility program to create, update, or replace an “FCB4”-prefixed image for the 3262 Model 5, 4248, or 6262 Model 14 Printers. For details about the “FCB4”-prefixed images, see either IBM 6262 Printer Model 014 Product Description or IBM 4248 Printer Model 1 Description.

The 3262 Model 5, 4245, 4248, and 6262 Model 14 printers each load a default FCB image into the buffer when they are powered on. The 3262 Model 5 default FCB image is an 11-inch form with 6 lines per inch, a Channel 1 on the third print line, and a Channel 12 on line 64. The 4245 default FCB image is an 11-inch form with 6 lines per inch and a Channel 1 on the first print line. The 4248 default FCB image is the last FCB image loaded. The 6262 Model 14 default FCB image is either the last FCB image loaded and saved or the default shipped with the printer.

STD1 sets line spacing at 6 lines per inch for an 8½ inch form; STD2 is a default FCB image that sets line spacing at 6 lines per inch for an 11-inch form. Channels for both images are evenly spaced, with Channel 1 on the fourth line and Channel 9 on the last line. See Figure 1 and Figure 2 for the format of the standard STD1 and STD2 images.

The standard FCB image for the 3800 Printing Subsystem, STD3, is included in SYS1.IMAGELIB during system installation. All models of the 3800 use FCB images whose names begin with "FCB3". Use the IEBIMAGE utility to create and modify FCB modules for the 3800 Printing Subsystem.
