Errors may occur any time Vortex is run, such as syntax errors
during compilation, problems during execution, or incorrectly formed
statements. These errors are logged with a timestamp to the error log
file, which is set during installation or with the command-line option
-e (here). The default error log is
c:\morph3\texis\vortex.log under Windows. The log file may be changed in the
texis.ini configuration file (see here).
If the log file cannot be opened, errors are printed to standard error
stderr). Each line of the
vortex.log has the following format:
NNN date script:line: Message in the function: dosomething
NNN is a 3-digit code indicating the general type and
severity of the error (not a unique identifier of the error).
The first digit indicates the severity: 0 is an error, 1 is a warning,
2 and higher are informational messages. The other 2 digits indicate
the type of error: 02-10 are file errors, 11 is out of memory, 15 is a
usage (syntax) problem, etc. The date and time of the error come
next, in YYYY-MM-DD HH:MM:SS format.. If applicable, the
script name and line that the error occurred on are given. The rest
of the line is a description of the error, possibly with the internal
C function name where the error occurred.
