# Parameter Values

The following table describes the values you can enter in the PARM field of the `EXEC` statement. In the absence of function action requests, the default action is print.

Value | Meaning | Default | Explanation
--- | --- | --- | ---
-C | Copy | None | Copies all the definitions from one configuration file to another file defined by `CONFIG2`. The file referenced by `CONFIG2` is initialized before copying starts.
-M ddn | Import | None, IMPORT | Reads the contents of the IMPORT file and apply to the CONFIG file. If you specify ddn, that DD name is used instead of IMPORT.
-N ddn | Export | None, EXPORT | Writes out the entire contents of `CONFIG` in export format to the EXPORT file. If you specify ddn, that DD name is used instead of `EXPORT`.

The following table describes the parameter values of the Configuration File Utility:

Value | Meaning | Default | Explanation
--- | --- | --- | ---
-D n | Debug | 2 | Specifies the level of message display. The value for n can be between 0 and 5, with 0 providing very few messages and 5 showing the hex displays of all the records processed.
-I xxx | Input DD name | CONFIG | Allows another DD name to be used in place of CONFIG.
-O xxx | Output DD name | CONFIG2 | Allows another DD name to be used in place of CONFIG2.
-P | Print | None | Prints out each recipe and trigger with the associated Backend, ESB Endpoint, Group membership, and Conversion rules.
-R | Read-only | Update | Opens the CONFIG file as read-only. If combined with Import, all the updates from the import operation are lost.
-T | Initialize | None | Allows the program to initialize the CONFIG file if the file does not contain the `Transformer_Anchor` structure at the beginning of the file. The Initialize request does not apply if you also specify read-only.
-V | Validate | None | Validates all the data structures for consistency and block identifiers (eyeball characters). If you specify -V -V, validation does not terminate after the first error occurs.
-X | Hex dump | None | Displays all the active definitions in the file in hex and does not show the relationships among the definitions.
-Z | Zero file | None | Resets the CONFIG file to empty before starting the requested processes. Note the warning as follows.

Note: Do not specify the Z option when importing data into a nonempty configuration file. Doing so destroys all the existing data in the configuration file.
