How to Type a Command with Its Parameter(s)
If you do not correctly type a command with its parameter(s), you can get partial
execution of the command (depending on the command issued) or an error message
with no command execution.
Correct DCL Command Format
The general DCL command format or syntax is as follows. The specific format varies
slightly depending on the command.
command[/option...] parameter
where:
command is the name of the command you want to execute.
/option... is one or more command qualifiers that modify the command.
parameter(s) is a file or files on which to act or data to be used by the
command.
or
command[/option...] in-filespec[/option...] out-filespec[/option...]
where:
command is the name of the command you want to execute.
/option is a command qualifier that modifies the command.
in-filespec is the file you want to access.
/option is a file qualifier adjusting the command’s action on the input
file. A file option applies only to the file it qualifies, whereas a
command option applies to all files the command executes.
out-filespec is the file that is to receive the results of the operation.
/option is a file qualifier adjusting the command’s action on the output
file.
Square brackets specify optional elements in a command line. A line such as
[NO]QUERY specifies that there can be two mutually exclusive options: QUERY
and NOQUERY.
