The CHAR function returns a one-character alphanumeric value that is a character in the program collating sequence having
the ordinal position that corresponds to the value of
argument-1. The type of this function is alphanumeric.
FUNCTION CHAR (argument-1)
- argument-1 must be an integer.
- The value of
argument-1 must be greater than zero and less than or equal to the number of positions in the collating sequence.
- If more than one character has the same position in the program collating sequence, the character returned as the function
value is that of the first literal specified for that character position in the ALPHABET clause.
- If the current program collating sequence was not specified by an ALPHABET clause, the value returned will be the character
in the ASCII character set occupying the ordinal position of the argument.
