What is High values and Low values in cobol

Any one of you can please explain to me what is high values and low values in cobol (EBCDIC).

I heard that low values are 00, and high values are FF. But I wanted to know what will happen when I do the following operations?

Hi,

First, You will not be able to Compile this.

You cannot move LOW-VALUES or HIGH-VALUES to a "PIC 9" field.

Once you remove these, the hex value in B and D are:

B = x'0000'
D = x'FFFF'

Hi Dave, Thank you very much for your information.
Can you please let me know in which scenarios we will move these LOW/HIGH Values?

Thanks!
Rat.

Ex:

Low values: we generally used to initialize variable.

High value : Suppose i want to get minimum value of an array variable which have 10 occurance so i will write me code like this.

Move high values to min-value

perform until i>10
If table(i) < min-value
move table(i) to min-value
end-if
compute i = i+1
end-perform.
