/INPUT=file-spec

 	Specifies an input file that contains one or more DCL
 	commands to be executed by the spawned sub-process.
 	Once processing of the input file is complete, the sub-process
 	is terminated.

 	If both the command-string parameter and the /INPUT qualifier
 	are specified, the command string is executed before the DCL
 	commands in the file specified by the /INPUT qualifier.
