Terminology and resolution of "restricted JFN" problem; and functions OPENF and TNX-GTJFN

[Jonathan Alan Solomon <JSOL at ECLC>]

Seems to me that you can do it without "restricting the JFN". If you
open the file "restricted access", which uses the following bit
(excerpt from INFO's JSYS node):

                    B29(OF%RTD)   Allow restricted  access  (i.e.,  allow
                                  only one process to access the file).


You will get the desired results (no other process can hack the file),
while at the same time, INFORMATION (ABOUT) FILE will show it. Note,
this is for the OPENF jsys, not for the GTJFN jsys. The JFN is
available, but the file is locked.
