Re: BPCS/36 4.4B to BPCS/400 6.1 Mixed Mode

The security level should NOT be a problem for the conversion programs 
themselves. What is wrong with version 4.0 BPCS is some third party add-on 
products (BIR, BBM?) have some direct calls to the MI instead of being nice 
and using defined interfaces. That is usually what breaks security level 40. 

In version 6, these products were eliminated and/or rolled into BPCS and the 
entire product was tested at level 40 (one NEWI bug was found in Full C/S and 
fixed several years ago) and it works fine. I would imagine it is not every 
program that fails, what you probably see is 1 or 2 programs doing illegal 
calls to programs below MI, and this is what causes violations. If this is 
not the case, could you mention what types of errors you saw? I have heard of 
no problems with the 2.09-6.1 running at level 40 systems, and did this 
myself without any OS/400 security errors, coming from a 2.09 database to 
6.0.04 BPCS, and then again to 6.1.00 BPCS.

The SSA Helpline is now running their system with all version 6 BPCS at level 
40, and the IBM reps who run BPCS at Rochester do it at level 50. BPCS CD is 
still run at level 30 because of the known issue with certain products.
