Coding - Comments to the sources, published in Scenergy # 1

        Comments to the source,

       published in Scenergy # 1

 As you probably remember - in Scenergy # 1
have been published in several sources
as an annex to the articles of the section
Coding. Prior to publication, I have checked all
sources - they are compiled and run
fine. However, I recently learned that
Some people have problems with
running these programs. It turned out that I
simply forgot to give the necessary explanations.
 Thus, for all who have tried to compile
and run the source code from the archives MusSinc.Z
and BumpSRC.Z and who they are buggy, explain,
you need to perform 3 conditions, especially
than they normally earn.

 1) Set the stack at # 5FFF. By
TASM'e default it is set to # 61A8,
I in all its programs using
memory starting at address # 6000 and therefore
I corrected myself of the BASIC loader TASM'a
CLEAR VAL "24999" on CLEAR VAL "24575." AND
I advise you to do the same. After
This patch source from the archive
BumpSRC.Z should normally earn.

 2) In the source code of the intro from the archive MusSinc.Z
I used a directive TASM'a. PAGE, for
In order to load a page in the right
my data. This is handy if you have a
512kb of memory and TASM sits in the upper memory
(Like me). However, if you have a 128kb and
TASM sits at the bottom - then no good
such podgruzki not lead. So you
need to comment out podgruzku music
Page (lines 78-80 file INTRO.A) and
after compiling manually from the STS to load
music (file P.VISION.C) to the bank # 16 in
at # C000 (sets the label MUSIC_PAGE
and MUSIC, respectively. Tags are defined in
file RES_EQUS.A).
 3) In the file MEMORY.A, in the end is
following construction:

        . PAGE # 57

        ORG # FEE4

        DEFW START_ADR

        ORG # FEFE

        DEFW START_ADR

        . PAGE # 10

        ORG START_ADR
 It "patch" STS to entering into it
start address corresponded to the starting
at the program.
 But the problem is that I have a STS
sits at the top of memory (and even uses
own screen:)) and bank where
it is located, given the number here:

        . PAGE # 57
 Usually, the STS is sitting in the bank # 17, so that
it is simply necessary to correct number
Bank of STS on the one in which you, this STS
ship.
 You can also just comment out in the
All source code macro call DISPLAY_INFO
(Usually this is the last line of file)
but then you lose control mechanism
memory allocation.

 After all these changes, all programs
should be compiled and run
normal.
