OpenVMS Alpha Porting and Migration

                Porting techniques developed by and employed
                 in TMESIS Software Ported to OpenVMS Alpha

      This page contains links to the source(s) for program(s) which
      demonstrate various techniques for porting OpenVMS VAX macro
      functionality to the OpenVMS Alpha platform. These techniques have
      been developed to allow existing macro-32 source programs to be
      ported to the OpenVMS Alpha platform with minimal code
      modification. In all of the examples, a common OpenVMS VAX and
      OpenVMS Alpha code base is assumed.

      This page is being constructed to serve as a FAQ site for macro-32
      porting. The FAQ is currently under construction. In the interim,
      porting techniques of immediate interest will be available here. If
      you have a question which you think should be a part of the FAQ,
      please forward it to: VAXman@TMESIS.COM for consideration.

      The porting techniques - code, examples, macros, etc. - available
      here are copyrighted and have deposits on file in the Library of
      Congress. You may use the code, examples, macros, etc. available
      here provided that any and all copyright notices remain in tact if
      you should employ it in your software. If you employ the techniques
      in any software which you will distribute, whether for free or for
      a fee, you must report its use to: VAXman@TMESIS.COM.

      Please take note that some porting techniques are not readily
      available without license. TMESIS Software will share these
      techniques only after the execution of a NDA (non-disclosure
      agreement). Sadly, the NDA requirement is the result of a long and
      costly legal dispute in which (in the humble opinion of this page's
      author) a sleazy, immoral, greedy, unethical and criminal copyright
      infringing organization sued claiming that the porting techniques
      available here (without the execution of a NDA) were their
      proprietary porting techniques. As you can see, these techniques
      are available so, as you may have guessed, the outcome of their
      (lie)suit was not in their favor. The techniques covered under NDA
      are provided under NDA to keep this organization from 'stealing'
      that which is not theirs - as they have tried in the past.

                   + LIB$TPARSE/LIB$TABLE_PARSE

                     Subtle differences in the OpenVMS implementation of
                     the finite table parsing run-time library may cause
                     a number of issues for porting an application using
                     LIB$TPARSE to the Alpha. How to maintain a common
                     code base for both OpenVMS VAX and OpenVMS Alpha,
                     while recognizing the differences in the
                     implementation of the finite state parser, is
                     covered here.

                   + EDITPC Instruction

                     The EDITPC instruction is a complex VAX string
                     instruction for the formatting of data. It is not
                     recognized by the Alpha amacro-32 compiler. If
                     you've never used the EDITPC instruction or if your
                     application uses EDITPC and you need to port it to
                     the Alpha, take a look here.
