That was true once upon a time but has not been true since about 1995. IND$FILE 
uses a 3270 sub-protocol called "structured fields" and can transfer up to 32K 
of binary data in a block.

It's still single-task and half-duplex, and layered into TSO, all of which 
makes it a lot slower than FTP, but it is NOT 3270 screen oriented.
