  Quick search of the help:

HOW CHARACTERS ARE INTERNALLY REPRESENTED
Internally, most computers store characters according to the ASCII format. 
ASCII stands for American Standard Code for Information Interchange. Characters 
are stored according to a numbered sequence, whereby A has a value of 65 
decimal, B a value of 66 etc. Several functions which manipulate characters 
follow.

    * CHR
      The chr or character position function returns the character associated 
with the ASCII value being asked, eg,
            chr( 65 )   will return the character   A
    * ORD
      The ord or ordinal function returns the ASCII value of a requested 
character. In essence, it works backwards to the chr function. Ordinal data 
types are those which have a predefined, known set of values.
      Each value which follows in the set is one greater than the previous. 
Characters and integers are thus ordinal data types.
           ord( 'C' )   will return the value   67
    * SUCC
      The successor function determines the next value or symbol in the set, 
thus
           succ( 'd' )  will return  e
    * PRED
      The predecessor function determines the previous value or symbol in the 
set, thus
           pred( 'd' )  will return  c
