/CREATE (default)
       /NOCREATE

    Creates a new file when the specified input file cannot be
    found. If the /MEMORY qualifier is specified and no input file
    is specified, the file created is the one specified by the logical
    name TEC$MEMORY. Normally, TECO creates a new file to match the
    input file specification if it cannot find the requested file name
    in the specified directory. When you use the /NOCREATE qualifier
    in the TECO command line and type a specification for a file that
    does not exist, TECO displays an error message and returns you to
    the DCL command level. The /CREATE and /NOCREATE qualifiers are
    incompatible with the /EXECUTE qualifier.
