As we approach the release date for some products currently under
development, we can expect a greater potential for conflict among
the following equally worthy goals:

  • To fix system bugs or shortcomings and provide enhancements in
    order to facilitate further game development.
  • To isolate game developers from system instabilities while the
    above goal is being met by the system developers.


The Programming Coordinators for each game can avoid disruptions
in their projects by taking the following steps:

  1. Create an isolated system directory for each project and load
    a stable copy of the system into it. Also create a backup for
    it and a directory for executables.

    Example:
    >md \games\ice\system
    >md \games\ice\system\old
    >md \games\ice\tools
  2. Make sure that all "where" files are written in terms of s:
    instead of \games\sci\system. Everyone's autoexec.bat file
    should contain the line "set sinclude=s:"
     
  3. To save a version of tools such as the compilers and
    interpreter, just copy them to your project's tool directory.
     
  4. To give your project's tools precedence over the main version,
    type in a line like the following one, which should be
    appended to all project members' autoexec.bat files:

    pushpath g:\games\ice\tools
     
  5. To freeze a version of the system for your project, type in a
    line like the following one:

    pushsys \games\sci\system \games\ice\system \games\ice\system\old

    This action might require the game to be rebuilt.

    Everyone working on the project should have s: mapped to the
    project's system directory. This can be done by editing the
    user login file using SYSCON on the net, or by appending to
    autoexec.bat a line like the following one:

    map s:=g:\games\ice\system
     
  6. If the above step is determined to be premature, it can be
    undone by typing a line like the following one:

    savesys \games\ice\system\old \games\ice\system

    This action might require the game to be rebuilt.
     
  7. Software updates should be performed and tested by the project
    coordinator at times that will not hurt the team's
    productivity, with enough time to rebuild, test and even revert
    and rebuild again if needed.

While the SCI development team will carefully test all system
changes to avoid introducing problems, its very flexibility makes
it impossible to test all cases. It will be the responsibility of
each project's coordinator to follow the above (or equivalent)
procedures.

I have provided the push*.bat and save*.bat files mentioned
above to facilitate this task; they are available in
x:\public\tools. We strongly recommend that all projects update
to the current system version as quickly as possible, since the
purpose of system changes is to correct bugs and provide
significant enhancements.
