C
C SUBROUTINE WITH TWO ENTRY POINTS :
C  CHTOI - CONVERT INPUT SINGLE CHARACTER CH (OF TYPE CHARACTER) TO AN
C          OUTPUT INTEGER I VIA THE LOOK-UP TABLE STORED IN CHSTR.
C  ITOCH - CONVERT INPUT SINGLE INTEGER I TO AN OUTPUT SINGLE CHARACTER
C          CH (OF TYPE CHARACTER) VIA THE LOOK-UP TABLE STORED IN CHSTR.
C A VALUE OUTSIDE THE ALLOWED SET OF 95 CHARACTERS RESULTS IN THE
C ALTERNATE RETURN BEING TAKEN, WITH THE VALUE ZERO RETURNED IN I FOR
C A CALL TO CHTOI, OR THE VALUE '?' BEING RETURNED IN CH FOR ITOCH.
C THE INTEGER REPRESENTATIONS ARE THOSE OF 8-BIT ASCII RANGING FROM
C 32 (FOR BLANK) TO 126 (FOR ~). SOME OF THE MORE EXOTIC CHARACTERS
C PRODUCE STRANGE (BUT NON-FATAL) CONVERSIONS ON SOME MACHINES.
