- PROGRAM: CRITP.COM, CRITR.COM
- VERSION: 1.00 January 16, 1987
- AUTHOR: KEITH P. GRAHAM
- CONTACT: PC-ROCKLAND (914) 353-2176 or (914) 353-2157
- DESCRIPTION: These two programs dynamically intercept requests for
- DOS critical handling. They try to avoid interferring
- when a program allocates the critical error handling for
- local use, yet try to recognize when a program is going
- to use the default routines. It will use a window panel
- for issuing critical error information and allows the
- user to "Abort Retry Ignore Fail" without causing
- scrolling of the current screen.
- LIMITATIONS: Program should be run under DOS 3.3. Choosing the "Fail"
- option under other versions of DOS is unpredictable.
- Program yields control to requests to redirect the
- critical handling interrupts. Sometimes a program
- will assign and reassign the vectors several times which
- may confuse CRIT. When CRIT is started it may not be
- in effect until a program is successfully loaded. The
- first command after a CRIT load may not pass to crit.
- A successful program execution reinitializes crit.
- CRIT windows will not restore graphics screens correctly
- and may appear as garbage if called up in Hercules
- graphics modes.
- USAGE: CRITR.COM is a memory resident program and requires
- no parameters. CRITP.COM is resident only during the
- execution of a single command. The CRITP command must
- be followed by any DOS command.
- When CRIT is loaded, it will watch for critical errors.
- If a program (such as chkdsk) redirects the critical
- error routines, CRIT will let it. If a program does not
- redirect the error routines, CRIT will pop a window up
- describing the error and giving four choices. The left
- and right cursor control keys will give CRIT the ability
- to select an option as does the first letter of each of
- the options. Pressing the return key confirms the
- selection. Pressing the Esc key passes you on to the
- original critical error handling. Pressing the escape
- or return will restore the screen and process your
- choice.
- COMMENTS: Version 1.00 is a test version for Stan Smith and
- users of PC ROCKLAND. It is not to be circulated to
- other BBS's. I would like reports on its operations
- and any problems. This was written at the request of
- Stan Smith to solve certain problems running QMODEM
- when a device not ready error is reported.
- I don't know if it works correctly on monochrome systems
- and would like reports. I will release a shareware
- version if I get reasonable reports as to CRIT's
- useability.
