Arguments

 

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 VAX, Alpha, and I64 systems.

      On Alpha and I64 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 and I64 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.
