361415 - Morris says....
361416 -
361417 -    1.  I followed the links a little.  Never did find the letter from
361418 -        Gary. The problem with DOS extenders is the code uses 16 bit
361419 -        pointers assuming each pointer points to a paragraph (16 byte
361420 -        chunk) of memory.  While some swapping could be arranged with a
361421 -        DOS extender, it won't allow a single file to grow larger than
361422 -        the current memory limits. ref DRT 1 0001
361424 -  ..
361425 - Gary's letter to Morris, cited in my record on 030728, asked for input
361426 - on using a "DOS extender" to increase memory for SDS, ref SDS 12 0001,
361427 - and was based on Gary's analysis on 030727. ref SDS 11 LM5O  Morris
361428 - does not seem to have responded to Gary; but, today, he sent a letter
361429 - to me answering the email to him yesterday that reviews Gary's
361430 - planning for a next version of SDS. ref SDS 14 VL4I
361432 -  ..
361433 - Does Morris' comment that a DOS extender will not "...allow a single
361434 - file to grow larger than the current memory limits," mean that....
361435 -
361436 -           a.  we could have a separate memory block assigned for each
361437 -               file?
361438 -
361439 -           b.  would these memory blocks be 640K or 1 MB?
361441 -                  ..
361442 -                 [On 030902 developed method for using Windows Start
361443 -                 command to accomplish this level of memory management.
361444 -                 ref SDS 15 0001
361446 -                ..
361447 -           c.  would this scheme support loading say 10 files with 500K
361448 -               each to actually use 5 MB of memory; or could the files
361449 -               be say 800K each to use 8 MB of memory?
361451 -                ..
361452 -               These are common scenarios with SDS, sometimes we could
361453 -               bump up to 15 or 20 files vary easily.
361455 -                ..
361456 -               What impact would this have on speed?
361458 -                ..
361459 -               What impact on fragmenting memory.
361460 -
361461 -                  Generally have to shut down w2k 1 - 2 times a day to
361462 -                  refresh memory, because we typically have a primary
361463 -                  session of SDS, and several other sessions for
361464 -                  working on different issues.  Assumes that opening
361465 -                  and closing these sessions leads to fragmented memory
361466 -                  that requires shutting down, depending on how heavy
361467 -                  the traffic has been.
361469 -                   ..
361470 -                  Would using extended memory in the manner under
361471 -                  discussion here increase the frequency of requiring a
361472 -                  shut down to refresh memory.
361474 -                   ..
361475 -                  Would increasing the total RAM in the computer have a
361476 -                  positive effect.  Currently, we have 500MB.  If we
361477 -                  went to 1 GB would the problem of fragmented memory
361478 -                  requiring shut down be expected to decline?  What
361479 -                  would this do to the speed of operations?
361480 -
361482 -  ..
361483 - While this is not a complete solution, it is big interim help while
361484 - the next version is being developed and debugged over the next five
361485 - (5) years, per planning on 030801. ref SDS 14 U87N  Gary called today,
361486 - and he feels that a five (5) year window is needed to use the current
361487 - version while the next version is developed.  This aligns with
361488 - planning on 950803 showing a 5 - 10 year development schedule.

380405 - Morris continues...
380406 -
380407 -    2.  The comments on design language are mostly moot with the speeds
380408 -        of current processors.  Write in the computer language that
380409 -        provides the most productivity for the programmer.  (Most
380410 -        likely C++, or some other higher language).  If writing for
380411 -        windows on a PC, then C++ has the best tools.  When PCs were
380412 -        slow, with limited memory, programming language and style could
380413 -        have an impact.  Now with huge memory spaces, and multi GHz
380414 -        processors, it is a non-issue.
380416 -  ..
380417 - Morris does not cite the location nor any specifics on comments for a
380418 - design language referenced in his letter.  Gary's record on 030727
380419 - discusses this subject at length. ref SDS 11 UY5H  Since this is the
380420 - only place where the subject has been addressed recently, and since
380421 - Gary's record was linked to the record on 030801, which Morris was
380422 - asked to review, ref SDS 14 QF91, assume that when Morris says he
380423 - followed some links, he is disclosing that he reviewed the heading

380434 - Morris' recommendation to use C++ for programming on a PC aligns with

430705 -    3.  The macros are a result of you refusing to learn a real
430706 -        programming language. I have suggested, and still suggest you
430707 -        learn C, and the macros are a thing of the past.
430709 -  ..
430710 - This aligns with Morris' suggestion above to use C++ for programming a

430714 - On 020110 Morris suggested creating SDS support for Com Metrics by
430715 - using the Microsoft macro language to enhance Word, Outlook, etc.
430716 - ref SDS 4 W559  This suggests that macros might be helpful for making
430717 - a program "extensible," which enables users to experiment in order to
