Re: SetLL *start

Barbara,

 Is there any good technical (not historical) reason that we still 
have any opcodes that can't use record formats and file names, for 
data files, interchangeably?  PF's can't contain multiple 
formats.  Multi-format LF's are relatively rare nowadays.  The only 
time it would require differentiation is if a MFLF is used.

 Is there a consideration to relax that requirement?
