Hello,

Is there some reason you want to make the intermediate move to "display format"?

Is the value to accumulate fifteen or is it really 21?
Hope this helps,

Hi Dick,

The value is 15 only. I want to use value 15 as index and want to increment the same.

I tried moving to 9(2) or comp variables,but the value is populating as '0050'


Thanks,
Archana

Hello,

What should happen when the input value is x'1C'?

Hello,

If the byte is a true binary value, you can move that one byte to the low-order byte of a 2-byte comp field.
01  comp-num         pic 9(4) comp.
01  comp-num-r redefines the-comp-num.
    05  filler          pic x.
    05  calc-byte       pic x.


in the procedure code,
move zeros to comp-num
move the input byte to calc-byte.

comp-num can now be used to subscript an array (or it can be incremented and then used as the subscript). it is not displayable, but is completely useful for calculating/incrementing.
Hope this helps,
d.sch.
