Answer / shobhit
The USROPN keyword causes the file not to be opened at
program initialization. This gives the programmer control
of the file's first open. The file must be explicitly
opened using the OPEN operation.
For example, if a file is opened and later closed by the
CLOSE operation, the programmer can reopen the file (using
the OPEN operation) without having specified the USROPN
keyword on the file description specification.
