Answer / abhishek kumar

In most of the cases files(*file) will be locked.
Reason: If any program is using that particular file.

Answer / samul

File object locked when file open in update mode or file
allocated excl in cl using cmd ALLOBJ.

Answer / sankar prosad mohanta

Abhishek is correct, but we can avoid this file locking,
specifying 'N' in 53 position of File Description Spec,
where the file is defined in the program.

Answer / keshar jain

@Shankar:
We can use N on position 53 in CHAIN if file is in Update
mode. For other mode we can't specify N.

Answer / ravi

When a file is declared in UF mode. U - Update, F - Fully procedural file.

When you do a read, it locks the particular record making it unavailable for any other programs. This is to protect the data integrity.

Once you do the update, the lock will be released. If you do not want the lock, you can specify Read(N), but you cannot update. You can also UNLCK opcode to release the lock.

Also, each time you update, you need to lock it.

If you do ALCOBJ you can lock it exclusively. This will not even allow basic functions on the object like read/display. And vice versa too. Any *SHRRD locks like read/display will not allow exclusive lock.

what procedure should we use to find whether the following operations are successful or not setll setgt chain read reade readp pls tell with example i'm not lazy to read the manual or not lazy to do anything.but sometimes i cannot understand the things given in manual in high level english its little bit complicated for me,i can't understand their way of writing thats why i ask these questions here and find the solution in simple words that i can understand thats the real reason sir.sorry if i had hurt you or disturbed you.please understand my situation.
