Formatting individual control blocks

In addition to the full LEDATA output which contains many formatted control blocks, the IPCS Control block formatter can also format individual Language Environment control blocks. The IPCS CBF command can be invoked from the "IPCS Subcommand Entry" screen, option 6 of the "IPCS PRIMARY OPTION MENU". For more information on using the IPCS CBF command, see the "CBFORMAT subcommand" section in z/OS MVS IPCS Commands, SA23-1382.


Syntax

>>-CBF--address--STRUCTure--(--cbname--)-----------------------><

address: The address of the control block in the dump. This is determined by browsing the dump or running the LEDATA VERBEXIT.
cbname: The name of the control block to be formatted. The control blocks that can be individually formatted are listed in Table 1. In general, the name of each control block is similar to that used by the LEDATA VERBEXIT and is generally found in the control block's eyecatcher field. However, all control block names are prefixed with CEE to uniquely define the Language Environment control block names to IPCS.

For example, the following command produces the output shown in Figure 1.

  CBF 100007B18 struct(CELCAA)
