When you get past the beginner stages of building an IBM Form, you will start building more and more complex computes and xPaths. Using the built-in compute editor and the built-in xPath editor, you'll want to add a bit of formatting to keep sane - some newlines and tabs for indentation.

You'll notice, though, those same computes and xPaths getting quite ugly in the source code.   They collect strings like this:


	

This is nothing to worry about.  The designer adds these control characters to the source code to keep track of the formatting you've entered.   They have no effect on the execution of your xPath or compute, and you can safely ignore them.

Essentially, the 
 is a carriage return and line feed combo (equivalent to a windows "\n" in Java or C).   The 	 is a tab character.
