Maintaining the SYS1.IMAGELIB Data Set

You will normally maintain SYS1.IMAGELIB using several programs in conjunction with IEBIMAGE. For example, you may find it necessary to rename or delete modules or to compress or list the entire contents of the data set. Programs such as PDF, DFSMSdss, IEBCOPY, IEBPTPCH, IEHLIST, and IEHPROGM should be used to help maintain SYS1.IMAGELIB. The program AMASPZAP can also be used for diagnosis purposes, and is described in z/OS MVS Diagnosis: Tools and Service Aids.

If you use programs other than IEBIMAGE for maintenance, you must specify the full module name. The module's full name consists of a 4-character prefix followed by a 1- to 4-character name that you have assigned to it. It is thus a 5- to 8-character member name in the form:

FCB2xxxx: an FCB module that may be used with a 3203, 3211, 3262 Model 5, 4248, or 4245 printer. Note that the 4248 accepts FCBs that will also work with a 3203, 3211, 3262 Model 5, or 4245 printer. Also note that FCB2 modules cannot be written using IEBIMAGE, although IEBIMAGE can use FCB2 modules as input for creating FCB4 modules.
FCB3xxxx: a 3800 FCB module
FCB4xxxx: an FCB module that may be used with a 4248 or 3262 Model 5 printer
MOD1xxxx: a 3800 copy modification module
XTB1xxxx: a 3800 character arrangement table module
GRAFxxxx: a graphic character modification module for a 3800 Model 1
GRF2xxxx: a graphic character modification module for a 3800 Model 3
LCS1nn: a library character set module for a 3800 Model 1
LCS2nn: a library character set module for a 3800 Model 3

where:

xxxx: is the 1- to 4-character user-assigned name of the module.
nn: is the 2-character user-assigned ID of the module.

Alias names are not supported by IEBIMAGE, so you should be careful if you use them. For example, if you change a module by specifying its alias name, the alias name becomes the main name of the new module, and the old module is no longer accessible via the alias but is still accessible via its original main name.
