R u talking about FILE-CONTROL of I-O SECTION. If so, it's used for file handling, which are used in the program. A logical name is given to every file and a DDname is assigned to it in this section.
| Code: |
ENVIRONMENT DIVISION.
CONFIGURATION SECTION.
INPUT-OUTPUT SECTION.
FILE-CONTROL.
SELECT IN-FILE ASSIGN TO INP
ORGANIZATION IS SEQUENTIAL.
SELECT OUT-FILE ASSIGN TO OUTP
ORGANIZATION IS SEQUENTIAL.
SELECT SYS-FILE ASSIGN SYST.
|
here IN-FILE is logical file name and INP is DDname of a file. Actual dataset is connected to program through JCL using this DDname. Hope u understood. Any query get back to forum. |

Hi Vinay,
It is very easy yaar , go to google search, give a keyword like[ I-O section+COBOL+mainframes] you will get many sites and select for the best one in that list which is more helpfull for you. |

Hello,
If you want current IBM documentation, much is available via the "Manuals" link at the top of the web page.
The "SEARCH" link near the top of the web page is to search for tpoics within these forums - it is not an internet search. It is a very good place to start as many questions are already answered within our forums. |
