INDDN

Multiple data sets

If you use multiple input data sets, specify only the ddname prefix (no nn) in this option. Note the following considerations:

• If you are using the INDSN option to dynamically allocate input data sets, LOADPLUS appends the data set number to the prefix that you specify. This prefix plus the highest data set number must not exceed eight characters.
• If you are not dynamically allocating input data sets, you must append nn to the ddnames in the DD statements in your JCL, where nn can be one or two valid alphanumeric or national characters.
• If you are not dynamically allocating input data sets, the prefix must allow LOADPLUS to differentiate the prefix from any ddnames that you specify in your JCL for other data sets. For example, if you specify an INDDN prefix of SYSU and your JCL contains a DD statement for your work data set that uses a ddname of SYSUT1, LOADPLUS assumes that the SYSU prefix refers to the SYSUT1 data set.

Additional considerations

Note the following additional considerations when you use this option:

• If you also specify INDSN on your LOAD command, LOADPLUS uses the value for INDDN as the ddname or ddname prefix when constructing your input data set DD statements. If any DD statements in your JCL match the INDDN value, LOADPLUS issues message BMC50460E and terminates.

  For a DSNUTILB load, LOADPLUS uses this value as the ddname.

• If you do not specify INDSN on your LOAD command and you use the default ddname SYSREC in your JCL, you do not need to use this option. However, if you want to use a ddname other than SYSREC, you must specify it both in this option and in your JCL.

Specifying the default

You can specify the default for the INDDN command option in your installation options module by using the INDDN installation option. LOADPLUS was shipped with a default value of SYSREC for this option. The command option overrides the default that is in the installation options module.
