Using the Model Setting › Modifying a Model

Modifying a Model

To add operands or new formats to an existing CP command, follow these steps:

• Determine the syntax of the command.
• Decompile the existing syntax model into a CMS file or extract the model of the command from the distributed model file
• Modify the syntax model.
• Compile the model under a test MDLTYPE.
• Create a test rule.
• Test the model.
• Activate command limiting.

Continuing with the previous VSNAP example, V/SNAP adds a format to the QUERY command. Add this new format to the QUERY command model:

FORMAT CLASS=ALL
    OPERAND VSNAP,5
FORMAT END

After establishing the MODEL setting of the ACF command, you can compile command models.

acf
ACF
set model
MODEL

Under the MODEL setting, you can use any of the following ACF subcommands:

• COMPILE
• DECOMPILE
• DELETE
• END
• HELP
• SET
• SHOW

The common subcommands END, HELP, SET, and SHOW are explained in the Administrator Guide. The other commands, specific to the MODEL setting, are explained in this chapter.
