can index be displayed .
can index be taken into some other variable?
in my code
01 ORIG-STRING.
05 STRING-1 PIC X(36).
05 STRING-2 REDEFINES STRING-1 PIC X(1) OCCURS 36 TIMES
INDEXED BY INDX1.


SEARCH STRING-2 when string-2 (indx1) = temp(i:1)
SET INDX1 UP BY 1.

now can i get this indx1 into some other variable. or can i display indx1?

Have you looked at the COBOL Language Reference manual at all?

For question 1, if you have a variable defined as USAGE IS POINTER you can use the SET statement to copy INDX1 into it.

For question 2, the manual specifically states USAGE IS INDEX variables cannot be put into a DISPLAY statement.

question 1. You can use any numeric variable to store the occurance value of an index.

Code:

05 ws-hold-sub               pic s9(4) comp.
05 ws-hold-index            usage is index.

set ws-hold-index to indx1.
set ws-hold-sub    to indx1.

Ws-hold-index will contain the value of indx1, and ws-hold-sub will contain a number for the occurance of inx1. Which you use would depend on what you want to do with in. You can display ws-hold-sub.

Hello dalib,

If you simply want to see the occurrence at which match occurred, use SET command to move the occurrence to a numeric variable as suggested above and DISPLAY it.

Thanks,
Arun
