Chapter 6 - Error and Warning 
Messages 
This chapter discusses errors and warnings that may result when the Type Tree 
Maker is run. 
Errors and Warnings 
When the Type Tree Maker finds a problem with a command, it creates either an 
error message or a warning message, depending on the severity of the problem. 
These error and warning messages that can be viewed from the Type Tree Maker 
window are also stored in the file ttmaker.log in your Mercator directory. When 
the Type Tree Maker finishes running, view the errors and warnings in the 
ttmaker.log file. 
The ttmaker.log file record contains the line number of the command that caused 
the error or warning message, followed by a message. An example of a warning 
message is: 
Warning 34 at line 3: Overwrote existing type (and possible 
subtree) 
See the Appendix A - Return Codes and Error Messages for a list of error and 
warning messages. 
Note  A general hint is to always check the spelling and syntax of the commands.
