How to split a variable in cobol

Hi all,
Iam encountering probelm while receiving data from the online screens. My problem is...

on the online screen data is like the below format

1) 4
2) 11
3) 12
4) 40
5) 116

The user may select one or more at a time and send it to back end
suppose if a user selects 4, 11, 116,40.. the data will be send to the backend as a whole ie.. 41111640.

now my job is to split it into the existing format ie 4, 11, 116, 40 and insert them seperately into data base.

I'm trying hard to find a logic for this. but can't.

Dileep

hi krishna,

i had tried the same logic .......

i defined the receiving fields as a table with depending upon clause for each variable.

Hi
The user may select one or more choices at a time from the online screen. The choosen values will be send to back end for insertion into data base.

Thanks & regards

What type of "the online screen" is it? IMS, CICS, ISPF, ...
What is the Backend? Batch job, CICS, IMS, , other ...

In any screen/display application, ims,cics,ispf the screen/display fields
will be seen by the application program as different fields/variables

so just design a consistent convention of exchanging multiple fields between application stages

a basic approach would be to define a structured array ...
flag,data were flag and data are suitable data types for example pic x, pic 10x

where the flag will be '0' for no data, '1' for data passed

and process data according to the flag

Hi,
The front end is a java screen and the back end is db2.
From online screen, the data will be passed to kustode(a cobol-db2 program), where it will receive the data and insert that in to database.

hope Iam clear now.

Thanks & regards

you can go for split the variable. The format was
Move variable1(1:2) to variable2. so that you can move the two byte of variable1 to variable2.

i think you can also do like this.

1)Since you don't have fixed format of the data that you are receiving from JAVA screens. Why can't you ask them in the required format i.e with the seperator ','. Based on the seperator you can do unstring and insert into database.

2)If they are not ready to send in the required format then you have to come up with some fixed length format i.e. say individual data length is 3, then your given string would become '004011116040'. And ask java screen developers to send the string in above format. Once you receive it you can use referrence modification to divide the data into individual peices.

Let's say your input on the screen 4,11,116,40. Store this into one variable WS-STRING, Now Appy Unstring function as below

Unstring WS-STRING into A(1), A(2), A(3), A(4),A(5) delimited by ' , '

then

it is splitted and A(5) will have space or blank value.

So while merging you can merge,

String A(1),(A2),A(3),A(4),A(5) delimited by size

Hello,

I must admit to being confused by this one - both now and when it was originally posted.

This looks more like a JAVA problem, how to get the JAVA screen to present the selected data in a form that allows the backend to split out the values correctly......

Hello,

Even so, the java code has separate fields ant when "forwarded" i would think they could have delimiters inserted. . .

Or, be force filled to fixed length. . .
