DISP-SHR means the file can be shared as long as it is not already
allocated for exclusive use somewhere else. DISP-SHRRR means shared for
read access. I'm going to read it, and you can read it too. This is more
restrictive than SHR, which also allows update. Most likely, you have
another job somewhere that does not specify any DISP in the file
statement. The default is exclusive use, which is exactly the opposite
of what it is for native code on the AS/400. I used to routinely make
the change that you're questioning on the old S/36, but it doesn't help
unless everybody cooperates.
