Error messages

UDO prints all error messages, warnings and hints that appear when converting the source file to files with the suffix .ul?. Each message is constructed the following way:

  Error:  : 
Warning:  : 
   Hint:  : 

If you want to avoid these errors, warnings and hints open the printed file, go to the printed line and try to find the error. Start with the first printed error and convert your source file once again. A lot of messages will disappear because they depend on earlier errors.

... called twice

The printed command was used twice or more inside the source file even if it is only to be used once.

... expected

UDO has expected the printed command. Please check if all environments were finished with the correct command or if a !begin_* is missing.

... followed by ...

You have finished an environment with an incorrect command or you have forgotten to finish it. Another possibility is that you have misplaced the !end_* command

... ignored inside preamble

It is only allowed to use the printed command inside the main part of the source file. That means you have to place it after !begin_document.

... ignored outside preamble

It is only allowed to use the printed command inside the preamble of the source file. That means you have to place it before !begin_document.

... maybe not available in (!LaTex)

The printed character cannot be used for LaTeX. Please try to use another character

... not active

... not available in ISO Latin 1
