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

    Format

      TPU$CLIPARSE  string ,fileio ,call_user

1  –  Returns

    OpenVMS usage:item_list
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    This routine returns the address of an item list.

2  –  Arguments

 string

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor
    Command line. The string argument is the address of a descriptor
    of a DECTPU command.

 fileio

    OpenVMS usage:vector_longword_unsigned
    type:         bound procedure value
    access:       read only
    mechanism:    by descriptor
    File I/O routine. The fileio argument is the address of a
    descriptor of a file I/O routine.

 call_user

    OpenVMS usage:vector_longword_unsigned
    type:         bound procedure value
    access:       read only
    mechanism:    by descriptor
    Call-user routine. The call_user argument is the address of a
    descriptor of a call-user routine.

3  –  Description

    This routine calls CLI$DCL_PARSE to establish a command table and
    a command to parse. It then calls TPU$PARSEINFO to build an item
    list for TPU$INITIALIZE.

    If your application parses information that is not related to the
    operation of DECTPU, make sure the application obtains and uses
    all non-DECTPU parse information before the application calls
    TPU$CLIPARSE. You must do this because TPU$CLIPARSE destroys all
    parse information obtained and stored before TPU$CLIPARSE was
    called.
