Internal System Error Message

Some of you may have encountered an alert which says

"Internal System Error! (Error Number)
1. Note what you just did.
2. Use Save As... to save your work.
3. Call Tech. Support.

As the Reference Guide says, this message indicates that RAM memory may have
been corrupted. This corruption may be caused by a number of different
things, including background utilities, a bad RAM chip, or -- the
unthinkable -- a bug in Ventura Publisher. In version 1.1, this message
occurred because many people ran Ventura Publisher with very little
conventional memory remaining. In version 2.0, Ventura Publisher requires
that at least 100K of conventional memory be available prior to starting the
program (less than 50K is required when running the Professional Extension).
This keeps temporary buffers from overflowing and possibly corrupting areas
of RAM memory.

If an Internal System Error does occur, do not continue modifying your
chapter. Immediately turn to Appendix C of the Reference Guide and follow
the steps given there exactly. These are repeated here:

1. Do not make any further changes to your chapter.
2. Use the Set Preferences option to change Keep Backup Files to YES.
3. Use the Save As option and save the chapter under a different name than
shown in the Title Bar.
4. QUIT from Xerox Ventura Publisher.
5. Re-boot your computer and then run Xerox Ventura Publisher again. Re-load
the chapter. If the message appears again, contact Xerox Technical support
for further assistance.

Some people have asked what the numbers which appear in the Internal System
Error messages alert mean. Here is an explanation.

System Error 19: Memory access outside of proper address range. Probably
caused by a bad data structure, software could not recover, or bug in code.

System Errors 1, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15, 16, 21, 82, 83, 150,
151: Ventura internal memory manager is corrupted. The numbers identify the
location within Ventura Publisher code where the error occurred. These
errors are more serious than System 19 and you may not be able to save the
chapter successfully.

System Error 25: Text line element error. Display is corrupted, but no loss
of data.

System Error 9999: Illegal serial number. The occurs in the network
environment where the user must have a legal serial number.
