File Concept
The Disposition Parameter in the JCL is Share ( DISP=SHR ) and Cobol program opens file in " Extend " mode. In this scenarion what will happen to that file?

The DISP=SHR in JCL means that the file is already existing and that it is not exclusively locked for your own use. Other user can still access this file. And the EXTEND in the COBOL program means that, when you open the file, the record pointer will be positioned on the last row of the record and every insert you'll make will be appended on the last position of the file.

We use comp field in cobol because when we want to store the data in binary form we use comp and the sign is placed in rightmost bit. c is used for +ve sign and d is used for -ve sign.
