By default, generator output is directed to a Generator Output tool, from which it can be printed, saved to a file, or copied and pasted to another application. Generator output can also be directed to a file, and different parts of the output can be written to different files:

filename 'name.txt' write
   /* generator output commands here */
close

Between filename and write there can be any generator commands, all of whose output goes to building up the filename to be used. There are also two useful commands here to prompt for the file name from the user. The first command, prompt...ask, opens a dialog asking the user for a string, and then outputs that string: this then is used in building up the filename, just as any output from any other keyword:

filename 
   prompt 
      'Enter file to output '
      id 
      ' to?'
   ask 
write
   /* generator output commands here */
close

The filename can also include information about directory paths.

The second command, prompt...askFilename, behaves similarly to prompt...ask but instead of prompting for a simple string, it provides a full file dialog. This enables the user not only to enter the filename but also to create new folders or select an existing filename.

All commands between write and close will output to the file specified. The close keyword immediately closes the output stream and writes the file. Commands after close will send their output to whichever output stream was in force before the filename command.

At the end of the whole generator a dialog will show how many characters were written to each file. If an error occurs trying to write to a file, the dialog will show the error message and output for that file will be redirected to its own Generator Output tool.
