Guidelines for Editing Comments in Source Code Files
When you edit a Vision source code file, be careful not to change or delete any of the comment lines that begin as follows:
/*# BEGIN
/*# END
Also, do not use the comment characters (/*#) to begin any 4GL comments that you add to a source code file.
Vision error processing uses the comment lines beginning with /*# to locate which sections of code contain errors. Editing or deleting any of these lines makes it more difficult to find and edit the errors.
