Options in interactive mode
In interactive mode, options that you enter on the initial command line override the value that you specified in your options file.
This value remains in effect for the entire interactive session unless overridden by a different value on a given interactive command.
For example, if you set the subdir option
to yes in your dsm.opt file, and you specify subdir=no on
the initial command line, the subdir=no setting
remains in effect for the entire interactive session unless overridden
by the subdir=yes value on a given interactive
command. However, the subdir=yes value specified
within the interactive session only affects the command on which it
is entered. When that command completes, the value reverts back to subdir=no,
the value at the beginning of the interactive session.



For example, if you set
the subdir option to yes in your dsm.opt or
dsm.sys file, and you specify subdir=no on
the initial command line, the subdir=no setting
remains in effect for the entire interactive session unless overridden
by the subdir=yes value on a given interactive
command. However, the subdir=yes value specified
within the interactive session only affects the command on which it
is entered. When that command completes, the value reverts back to subdir=no,
the value at the beginning of the interactive session.
