Hi

This High and Low Values are Figurative constant and are reserved words that name and refer to specific constant values.

HIGH-VALUES
Represents one or more occurances of Character that has highest ordinal position in collating sequence used.
For EBCDIC collating sequence , the character is X'FF';
For other collating sequence, the actual character used depends on the collating sequence indicated by the locale

LOW-VALUES
Represents one or more occurances of character that has lowest ordinal position in collating sequence used.

Regards
For EBCDIC collating sequence, the Character is X'00';
