Use REPLACE to replace the contents of one or more locations with
 new  data in terms of the current mode settings.
 Before performing the replacement, the REPLACE  command  confirms
 the contents of the specified locations.

 Replacing Data:
 _________ _____
      When you replace ASCII or numeric data, the number of replacement
      entries cannot exceed the number of existing entries.  This means,
      for example, that if you confirm the contents of six consecutive
      locations, you can replace the contents of only those six locations.
      If the number of replacement entries is less than the number of
      existing entries, the remaining locations are filled with zeros.

      In addition, PATCH truncates replacement entries if  they  exceed
      the  limit imposed on them by the current length mode.  For ASCII
      characters, the right-most characters are discarded.  For numeric
      data, the left-most digits are discarded.

 Format:

      REPLACE location = current-contents [,...]
      new-contents
              .
              .
              .
