Appendix A - Return Codes and Error 
Messages 
This appendix discusses error and warning messages that result when generating 
a type tree using the Type Tree Maker. 
When the Type Tree Maker finds a problem with a command, it returns either an 
error message or a warning message, depending on the severity of the problem. 
These error and warning messages, viewable from the Type Tree Maker, are also 
stored in the install_dir/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).
Type Tree Generation Error Messages 
The error and warning messages are listed in the following tables. The hints show 
some likely causes for the error message. 
Note  A general hint is to always check the spelling and syntax of the commands.
