I've got a dBase II program that's giving a bit of trouble.  Here's
a portion of it.  It's supposed to be a menu that reads an option entered
by the user.  As long as a valid option is entered, the program functions
correctly.  When an invalid option is entered, the program abends and
returns the user to the dBase II prompt.
=========================================================================
SET ECHO OFF
SET EXACT ON
SET TALK OFF
SET BELL OFF
SET CONFIRM OFF
SET INTENSITY OFF
STORE ' ' TO OPTION
STORE ' ' TO EXIT
ERASE
DO WHILE EXIT = 'F'
  @ 1,35 SAY 'CLASS ABCD'
  @ 3,10 SAY 'LOGIN CODE'
  .                          Format the rest of the screen.

READ
DO CASE
   CASE OPTION = 'K'
      DO NUCH
   CASE OPTION = 'N'
      DO COMD
   .                        Based on user entry DO some specified routine.
   .                        Now, here's where we're having problems.
   .                        It's with the OTHERWISE command:
   OTHERWISE
   ?  CHR(7)
   @ 24,3 SAY '*** INVALID OPTION ***'
ENDCASE
STORE ' ' TO OPTION
STORE 'F' TO EXIT
ENDDO

I'd appreciate any help anyone can offer.  Thanks a lot.  Also, we've tried
to find some documentation to answer the problem -- and were unsuccessful.
If you have some, could you reference it?  Again, thanks.
