/OBJECT[=filespec]
       /NOOBJECT

    Creates or omits an object module. It also defines the file
    specification. By default, the compiler creates an object module
    with the same file name as the first input file. The default file
    type for object files is OBJ. No wildcard characters are allowed
    in the file specification.

    The /OBJECT qualifier controls the defaults applied to the output
    file specification by the placement of the qualifier in the
    command line.
