#1: How DD name is mapped to File-control in cobol Author: kanitha-mvs,

Hi,

In most of the jobs, JCL is having a DD name and the cobol program has some prefix added to the DD present in JCL. How is this mapping done?

Eg: In jcl its like "XXX DD DSN=A1.EX.DSN, "
In FILE-CONTROL of cobol, its like

FILE-CONTROL.
SELECT COB-FILE ASSIGN TO UT-S-XXX.

Thanks.

perform a search on the programmers guide for your cobol version on the keyword assignment-name.

follow the links and read the explanations given.

This link will list all COBOL Manuals. Find the one for your cobol version and environment.

Dick has given a correct direction, However, for my .02$... percept this

Code:

SELECT COB-FILE ASSIGN TO UT-S-XXX.

Code:

SELECT logical-file-name ASSIGN TO UT-S-DDname.

DDname is common between COBOL program and JCL so that's where connectivity comes in.

In UT-S, "UT" is meant for "Utility-Only Access" and "S" for sequential. They are optional prefixes.

Hi Kolusu,

I've never heard if "UT" stands for "Unit Transfer", what I know is

First part in DDNAME: - Device Class
UT stands for Utility (Tape or Sequential Disk, and they should be OPENed in input mode as far as COBOL goes)
DA stands for Direct-Access (disk)

Second part in DDNAME: - Method of Organization
S

Anuj Dhawan,

I couldn't find the documentation which mentions UT as unit of transfer. I remember reading it as unit of transfer.

Anyway if any of the senior members know the exact definition it would be great

Sure Kolusu, I look forward to that. Meanwhile if I found something on that I'll post here.

I know it's very trivial to know this in the time of Enterprise COBOL but sometimes curiosity kills you... Smile

Have a good one,
