Iam having a numeric field "23.456" or "238.768" and have to read the data from right to left.

While reading the numeric field the fourth byte should always contain "." . if the "." is not present in the fourth byte we need to display an error message.

Could you please let me know what is the approach to complete this requirement.

Thanks for the help.

Code:
01  a-nice-name..
    05  name-for-first-part-of-number PIC X(3).
    05  FILLER PIC X. 
         88  field-has-decimal-point VALUE ".".
    05  name-for-second-part-of-number PIC X(3).

IF field-has-decimal-point
AND name-for-first-part-of-number NUMERIC
AND name-for-second-part-of-number NUMERIC
    do your stuff
END-IF

No. There is nothing to check for a COMP-3/PACKED-DECIMAL field, as you cant have an explicit decimal-point (.) there, only an implicit one (V).
