Hi Bernd, glad to see you've joined this ML.

Obviously my experience of both the IBM architecture and the innards of 
FPC is limited, but my opinion is that the only achievable goal is to 
first concentrate on ASCII, and later port to EBCDIC since this could 
result in significant changes to the compiler frontend etc. However, 
I'll obviously defer to consensus.
