Initializing Your Region Using the SOLVE Program › NMDRVCTL Data Set

NMDRVCTL Data Set

When SOLVE executes, it opens and reads the data set associated with the NMDRVCTL ddname to obtain parameters. This section describes how to specify the contents of NMDRVCTL.

The NMDRVCTL DD statement points to the data set that contains control statements for SOLVE. These control statements specify:

• SOLVE options
• PARM information for the target program
• Data set or SYSOUT allocation requests

The data set must have the following attributes:

• Fixed (blocked or unblocked)
• LRECL 80
• Any valid block size

The data set can be sequential or a partitioned data set (PDS) member, or a concatenation of these. For example, it can be a member in SYS1.PARMLIB.

The control statements must be in the following format:

• All control statements must be in uppercase.
• Only columns 1 through 72 are examined. If line numbers are desired, they can be in columns 73 through 80.
• Blank lines are ignored.
• Any line with an asterisk (*) as the first non-blank character is treated as a comment and ignored.
• Other lines must contain valid SOLVE commands (see the following section for details of these commands).

  Only one command is allowed per line. Commas can separate the operands of a command. Comments can trail on the lines if they are separated from the commands and operands by a blank.

• The commands for data set and SYSOUT allocation can span several lines. In this case, the plus sign can be used as a parameter to indicate that the next line is a continuation of the current command.
