I do not understand this point. If you know the name provide it to the program using linkage section or by some files??

Post your requirements clearly, so that you will get a better chance of getting the results.

actually the thing is that there are a lots of gdg's and i need to find out the length of the names of all the gdg's
so i want the names to be stored in a file with all related information of gdgs so that one by one i could read them and find out the length of each gdg and display them.

but the main thing is that i have to find the length of the gdg name.

I'm not a COBOL guy, but isn't there an INSPECT verb? Something like

INSPECT WS-DSNAME TALLYING WS-SPACE-CNT FOR ALL SPACES.

then

WS-DSNAME-LENGTH = 44 - WS-SPACE-CNT.

sorry i think i am was not able to clarify my requirement
actually i dont have the gdg's names in any file
i have to read them from the system(catalog table)
and get there dsn in a cobol variable on which i can use inspect.

Maybe you should take a couple of steps back and described your process workflow. What's the input? What's the output? What are the necessary steps to achieve your desired results? I don't really see why you'd want to write a COBOL program instead of using some basic scripts or some standard utilities, or both.

Hello,

actually i dont have the gdg's names in any file
i have to read them from the system(catalog table)
If you list the catalog entries, you can place the output in a file (ratgher than the print queue) and then read that file into your cobol code and calculate the length of each dsn.
Hope this helps,
d.sch.
