LOW-VALUES and HIGH-VALUES are figurative constants that represent the lowest and highest possible values for an alphanumeric data item. You would use them anytime you want to set or compare a data item to "all bits off" or "all bits on" values.  On system 390, LOW-VALUE = X'00' or all binary zeroes. HIGH-VALUE = X'FF' or all binary ones.

Generally used for initialization. HIGH or LOW values are assigned as per the collating sequence.

High-Values & Low-Values are ALPHANUMERIC Figurative Constants in COBOL. These are non printable characters which are having highest and lowest values respectively in a collating sequence.
