-
-
- This program is a resident (TSR) utility that traps critical errors and
- attempts to handle them in an intelligent way. It replaces the normal
- "Retry, Ignore, Abort" prompt. The program automatically attempts to
- retry failed operations when you are not there to press the "R" key.
-
- It draws on all available information to present a complete error
- description to the user. If the operator does not respond within 10
- seconds the program will automatically take the action suggested by DOS.
-
- DOS version 3.0 or later is required to use this program.
- Once resident, FATAL used about 3800 bytes of RAM.
-
-
- Usage:
- FATAL/I ;install FATAL in memory.
-
- FATAL/U ;un-install, remove FATAL from memory.
-
- FATAL/C ;display critical error counters.
-
- FATAL/Z ;reset error counters to zero.
-
-
- The FATAL program will take over critical errors that are not directly
- handled in a later program. It is careful to preserve any replacement
- error handler used by an application program. Because of this, it is
- advised to load FATAL as an early TSR, before any others that also set
- up critical error handlers. In multi-tasking systems you may need to
- load a copy of FATAL into each memory partition.
-
- NOTE: If you are running the LANtastic network, you must load FATAL
- *before* calls to SERVER and probably also before REDIR and
- LANBIOS. Otherwise a sharing violation will be trapped on the
- server rather than on the offending workstation!

- SourceWare: What is it?
- -----------------------
-
- SourceWare is my name for a unique concept in user supported
- software.
-
- Programs distributed under the SourceWare concept always offer source
- code.
-
- This package can be freely distributed so long as it is not modified
- or sold for profit. If you find that this program is valuable, you
- can send me a donation for what you think it is worth. I suggest
- about $10.

- Why SourceWare?
- ---------------
- Why do I offer source code? Why isn't the donation manditory? The
- value of good software should be self-evident. The source code is
- the key to complete understanding of a program. You can read it to
- find out how things are done. You can also change it to suit your
- needs, so long as you do not distribute the modified version without
- my consent.

- If you modify this program, I would appreciate a copy of the new
- source code. I am holding the copyright on the source code, so
- please don't delete my name from the program files or from the

- Revision History
- ----------------
-
- 7-20-89 v1.0
- Initial coding and release.
-
-
- 7-31-89 v1.1
- Changed all display code to use BIOS calls exclusively. The initial
- version used the DOS function 9, but this caused problems when
- standard output was redirected: the FATAL messages were also
- redirected!
-
- Added screen save and restore operations; original user screen is now
- preserved after fatal error processing (text modes only). BIOS calls
- are used for compatibility with all system types.
-
- Corrected an error that caused application program error handlers to
- be replaced. FATAL is supposed to replace only the standard handler,
- leaving application error handlers in place.
-
-
- 8-2-89 v1.2
- Changed keyboard input functions to use BIOS calls rather than DOS
- calls. This prevents a crash if standard input has been redirected
- from a file at the time a critical error takes place.
-
- Slight reduction in RAM requirement.
-
- FATAL now removes itself from memory if run a second time. Please
- don't do this if you have any resident programs loaded after FATAL.
-
- Added /L command line option to bypass license messages.
-
-
- 8-14-89 v1.3
- Added internal counters for number of critical errors and number of
- automatic retries. Each possible error message is counted for later
- reporting.
-
- New FATAL/C option produces a detailed report of all error counters.
-
- New FATAL/I option performs initial installation.
-
- New FATAL/U option un-installs fatal if possible.
-
- Fatal now hooks the DOS services interrupt in addition to the timer
- tick interrupt. On very fast machines it was possible to miss a
- critical error during the first 55 miliseconds of program execution.
-
-
- 12-26-89 v1.4ß1
- Shortened automatic retry delay from 30 seconds to 10 seconds.
-
- New FATAL/Z option to zero all error counters.
-
- Added new logic to properly handle nested calls to COMMAND.COM and
- shells to COMMAND.COM from application programs.
-
- Improved the ability of FATAL/C to locate the resident portion, even
- when being called by an application that takes over the critical
- error interrupt.
-
-
- 03-29-90 v1.4ß2
- Added some additional error messages.
-
- Corrected "stray" character in prompt.
-
- Widened error display window to allow better formatting of longer
- error reports.
