    File I/O routine. The fileio argument is the address for a
    descriptor of a file I/O routine.

 call_user

    OpenVMS usage:vector_longword_unsigned
    type:         bound procedure value

3  –  Description

    The TPU$PARSEINFO routine parses a command and builds the item
    list for TPU$INITIALIZE.

    This routine uses the command language (CLI) routines to
    parse the current command. It makes queries about the command
    parameters and qualifiers that TPU expects. The results of
    these queries are used to set up the proper information in an
    item list. The addresses of the user routines are used for those
    items in the list. The address of this list is the return value
    of the routine.

    If your application parses information that is not related to the
    operation of TPU, make sure the application obtains and uses
    all non-TPU parse information before the application calls the
    TPU$PARSEINFO interface. This is because TPU$PARSEINFO destroys
    all parse information obtained and stored before TPU$PARSEINFO
    was called.
