I know that Siemens BS2/OSD mainframes use the same machine instructions
as the IBM mainframes, e.g. UNPK, PACK, AP, DP, MP, SP, CMP, MVZ, MVO
for packed decimal arithmetic. The differences are in the compilers and
run-time systems.
The problem in this case is most likely the number of assumed digit in
intermediate results, like Vince Coen already stated.
