INDSN

Use this option for one or more of the following reasons:

• When loading data from UNLOAD PLUS by using FORMAT BMCUNLOAD
• To load data from different input data sets by updating only your syntax cards
• To eliminate the need to override SYSREC DD statements in your cataloged JCL procedures (PROCs) with SYSREC DD statements in your JCL

The input data sets must already exist and must be cataloged tape or DASD data sets.

Restrictions

The following restrictions apply to using the INDSN option:

• You cannot use this option when loading data from a batch pipe.
• You cannot specify multiple data sets that are on a stacked tape.
• You cannot specify any parameters for these data sets (such as VOLSER, DCB, or UNIT) other than the data set name.
• If you include SYSREC DD statements in your JCL when you specify this option, LOADPLUS issues message BMC50460E and terminates.

Additional considerations

The following additional considerations apply to the INDSN option:

• You can specify a GDG name as your data set name. LOADPLUS interprets a digit, plus sign, or hyphen following an open parenthesis in dataSetName as an indication that the data set name is a GDG name.
• You can specify a PDS name as your data set name as long as you include a member name. LOADPLUS interprets an alphabetic character following an open parenthesis in dataSetName as the beginning of a PDS member name.
• You can specify a dummy data set by specifying INDSN('NULLFILE').
• You can use the INDDN option to override the ddname prefix for your input data sets during dynamic allocation.
• Because each data set name that you specify with INDSN is assigned to a separate SYSREC data set, all restrictions and considerations that apply to multiple SYSREC data sets apply to specifying multiple data set names on the INDSN option. For more information, see SYSREC-data-sets-in-LOADPLUS.
