What is HIGH-VALUE and LOW-VALUE in Cobol

shreevamsi

Hi,

What is the basic difference between 'HIGH-VALUE' and 'LOW-VALUE' in cobol.

Some times in cobol, I have seen
MOVE LOW-VALUE TO WS-VARIABLE.

I remember i have seen HIGH-VALUE in the searches but never moved to a variable

What exactly are the both for??

HIGH-VALUE/HIGH-VALUES
Represents one or more occurrences of the character that has the
highest ordinal position in the collating sequence used. For the
EBCDIC collating sequence, the character is X'FF'; for other collating
sequences, the actual character used depends on the collating
sequence. HIGH-VALUE is treated as a nonnumeric literal.
LOW-VALUE/LOW-VALUES
Represents one or more occurrences of the character that has the
lowest ordinal position in the collating sequence used. For the
EBCDIC collating sequence, the character is X'00'; for other collating
sequences, the actual character used depends on the collating
sequence. LOW-VALUE is treated as a nonnumeric literal.

U CANNOT MOVE LOW OR HIGH VALUES TO "PIC 9" FIELD
CAN MOVE ONLY TO "PIC X" FIELD

MOVE LOW-VALUE TO WS-VARIABLE-1.
MOVE HIGH-VALUE TO WS-VARIABLE-2.

RESULT:

WS-VARIABLE-1= x'0000'
WS-VARIABLE-2= x'0000'
