You should not create too many global variables under a single global variable stem. If you do, you will no longer be able to view the global variables under OPSVIEW option 4.8, or access them using the OPSVALUE function.
The absolute product limit is 32,768 variables under a single global variable stem. However, in practice, we strongly recommend that no more than 10,000 global variables exist at any given instant under a single global variable stem.
Note: There is a restriction in viewing too many variables when going cross-system. Trying to access several hundred variables may cause a time-out on the MSF link.
