The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Symptoms: When the customer saves a WordPerfect 5.1 document containing a section symbol (Alt-21 or Ctrl-V, 4,6) as a DOS text file and then retrieves the file back into WP, the section symbol will display as Ctrl-U (^U). Solutions: The Control character for ASCII value 21 is ^U. The first 32 ASCII values have dual and sometimes triple meanings. DOS sees this character as a Ctrl-U (^U) whether the character is displayed as a section symbol or as ^U. The value of the character is the same. Since there is a ^U merge code in WP, it is safer for the WP program to assume that a 21 or ^U coming from DOS is a ^U. If the user wants a section symbol after the DOS text file is retrieved into WP, they will need to search for ^U and replace the character with Alt-21.
