Structure of a VSE JCL Configuration File

A VSE JCL configuration file is a text file that contains a number of name-value pair entries, with each entry on a separate line. Blank lines or lines beginning with an asterisk (*) are treated as comment lines.

The format of the name-value pair entries are shown below.

For devices:

device_id      id
device_type    type

where:

id is a three-digit code specifying the device address
type is one of PRINTER, READER, PUNCH, DISK or TAPE.

For logical units:

assgn_lu        lu
assgn_device    device

where:

lu is the logical unit to use.
device is the device to assign to the logical unit lu.

For standard labels:

dlbl_dd         dd
dlbl_dsn        dsn

where:

dd is the label to use.
dsn is the data set name to assign to the label dd.
Note: There is an addtional name-value pair entry for defining partitions, but specifying it has no effect.
