# Argument Substitution

You can pass transfer properties to the executable command as substitutable command line arguments.

You can enter any of the following listed argument names after the COMMAND entry in the configuration file.

Argument Name | Data Substituted
--- | ---
&TYPE | Send or Receive
&SOURCE | Initiator or Responder
&STATUS | Success or Failure
&RC | Numeric return code (0 if successful)
&FILENAME or &DSN | Local file name
&PROCESS | Process name
&NODE | Node name (or NODE if no node can be found)
&IPADDR | IP address (or IPADDR if no IP address can be specified)
&TRN | Local transaction number

In the following example, the file name and type of the transfer request are substituted for the &FILENAME and &TYPE arguments and passed to the executable as command-line arguments.

`COMMAND=cmdfile.com &FILENAME &TYPE,`
