Question: What is the SYSLOG.DAT file for? 

The SYSLOG.DAT file is a low level logging file used by Citect. This file is in the Windows directory (normally C:\WINDOWS). Citect will log system type errors and other debugging information to this file. You should check this file occasionally to see if Citect has found any system errors.

Citect will write to this file until it reaches about 300k in size. Citect will then rename it to SYSLOG.BAK and create a new file. This limits the maximum logging information to 600k and will reduce the space required (on your hard disk). You can adjust the size of the SYSLOG.DAT file with the CITECT.INI option [DEBUG]SysLogSize=n, where n is the size in kilobytes.

You can also log information to this file by using the Cicode function ErrLog(). This is a useful function for adding error tracing into your own Cicode functions. See online help for details on ErrLog() function.
