Hi
I'm new to coding. I have tried to inquire an online file with its logical file name
//SYSIN DD *
//FILE INQUIRE filename

But I'm getting below error
Invalid input in SYSIN - File operation requested is invalid in:
FILE INQUIRE filename

Can any one tell me the command which has to be given in SYSIN.

Welcome.
1.You need to provide complete JCL that you have tried.
2. Do you have CAFC installed?
3. Take a look at IDCAMS VERIFY
4. Easiest way,Write a small Cobol Program

But you did not provide any SYSIN command.

And it is not totally clear what you are attempting. Assuming that you want to inquire on a file in a CICS region, you can do so from a batch job with
Code:
// F <cicsapplid>,'CEMT I FI(????????)'
where ???????? is the file name (DD name) the CICS region uses for the file. Also, be aware that commands in batch JCL are NOT issued as part of step execution but rather are done first before the job executes.

Going forward, if you don't have CAFC or some other File Management package, is to write an EXCI program, which links to the target region, where another program resides and this program must issue an INQUIRE FILE API. Then, the CICS program returns the EIBRESP to the EXCI program (in the COBOL RETURN-CODE Special Register) and then you can scrutinize this value.

HTH....
