VMS Help RTL Routines, LIB$, LIB$TABLE_PARSE, Arguments  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 argument-block

    OpenVMS usage:unspecified
    type:         unspecified
    access:       modify
    mechanism:    by reference

    LIB$T[ABLE_]PARSE argument block. The argument-block argument
    contains the address of this argument block.

    The LIB$T[ABLE_]PARSE argument block contains information about
    the state of the parse operation. It is a means of communication
    between LIB$T[ABLE_]PARSE and the user's program. It is passed as
    an argument to all action routines.

    You must declare and initialize the argument block.

    LIB$T[ABLE_]PARSE supports the following argument blocks:

    o  A 32-bit argument block that accommodates longword addresses,
       values, and input tokens on both VAX and Alpha systems.

       On Alpha systems, this argument block also accommodates a
       numeric token whose binary representation is less than or
       equal to 2**64.

    o  A 64-bit argument block that accommodates quadword addresses,
       values, and input tokens on Alpha systems.

 state-table

    OpenVMS usage:unspecified
    type:         unspecified
    access:       read only
    mechanism:    by reference

    Starting state in the state table. The state-table argument is
    the address of this starting state. Usually, the name appearing
    as the first argument of the $INIT_STATE macro is used.

    You must define the state table for your parser.
    LIB$T[ABLE_]PARSE provides macros in the MACRO and BLISS
    languages for this purpose.

 key-table

    OpenVMS usage:unspecified
    type:         unspecified
    access:       read only
    mechanism:    by reference

    Keyword table. The key-table argument is the address of this
    keyword table. This name must be the same as that which appears
    as the second argument of the $INIT_STATE macro.

    You must only assign a name to the keyword table. The
    LIB$T[ABLE_]PARSE macros allocate and define the table.
