Actually Index is a register variable in COBOL, which will tell about the displacement ; as Subscripts are telling about the occurrences only. And there will be no need to declare them in Working Storage section.

What is Load module & Link edit and How will it work Dynamic call?
Normally we are using Dynamic call. What will happen when COBOL program compilation & execution.
ramesh4greek
- Jun 11th, 2010
Load Module: The object code converted into Load Module (Machine readable form) by using Link edit that's common in COBOL. But in Dynamic call, first we have to submit the sub progs later we can use that in Link section in COBCOMP. That's the procedure.

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.
