Transfer between mainframe (z/OS) and distributed systems has never been an issue or mess.
It is a mess, I submit as evidence the difficulty doing a round-trip transfer and ending up with the same data you started with.
Fixed length records and binary transfer is OK, anything else can be a problem.
EBCDIC<->ASCII translation can be a problem depending on the code pages involved. Usually it works acceptably but it's hard to guarantee.
I don't think IBM provides anything that does variable length records in binary mode correctly for a round trip. It's a while since I looked at FTP, but last I looked the RDW option only worked for transfers from the mainframe. You couldn't use it to write VB data back to the mainframe.
So with or without translation, FB or VB gives you 4 scenarios, only 1 of which is truly reliable.
