The library data sets and modules needed by the message editing utility are installed as part of the CICS® Transaction Server for z/OS®, Version 3 Release 1 installation process. (The utility data sets are outlined in Utility data sets.) However, before you can use the message editing utility, you must define the ISPF index of the utility data sets. This is described in Defining the utility data set index.
The following partitioned data sets are used by the message editing utility.
These data sets, except CICSTS31.CICS.SDFHTLIB, are created automatically when you install CICS Transaction Server for z/OS, Version 3 Release 1. The CICSTS31.CICS.SDFHTLIB data set, and some control files, are created automatically when you run the message editing utility. The control files are called target_data set_index.MEUCNTLx, where:
If, when installing CICS, you change the location of the initial dialog module from CICSTS31.CICS.SDFHCLIB(DFHMEUCL), you must edit DFHMEUCL and change the PROC statement. The PROC statement specifies the location identifier of the utility, and is used to find the initial program for the message editing utility. As supplied, the PROC statement is as follows:
PROC 0 MEULIB(CICS640)
If you want to invoke the message editing utility with a different data set prefix, you can pass the data set name from the command table. Alternatively, you can use the MEULIB(xxxxxxxx.xxxxxxxx) parameter on the CLIST command, where xxxxxxxx.xxxxxxxx is the prefix that you want to use. For example:
TSO EX 'CICSTS31.CICS.SDFHCLIB(DFHMEUCL)' 'MEULIB(mymeu.prefix)'
where mymeu.prefix is the prefix to be used for the utility data sets. MEULIB need only be specified if the prefix has been changed from the default.
