Hmmmmm...

Isn't there a technique where you can do a segmented load of a file from
BASIC.SYSTEM?  I think if you know the file length, you can do something
like...

]BLOAD /BIGDISK/BIGFILE,A$2000,L$4000,TTXT
]CREATE /LITTLEDISK/LITTLEFILE.1,TTXT
]BSAVE /LITTLEDISK/LITTLEFILE.1,A$2000,L$4000,TTXT
]BLOAD /BIGDISK/BIGFILE,A$2000,L$4000,B$4001,TTXT
]CREATE /LITTLEDISK/LITTLEFILE.2,TTXT
]BSAVE /LITTLEDISK/LITTLEFILE.2,A$2000,L$4000,TTXT

Or something like that...I haven't tried it...I may have the wrong
parameter for the starting position in the big file (B$4001), or the wrong
syntax for the CREATE command. But I think that feature is built in to
ProDOS and BASIC.SYSTEM.

You need the file length (look at the end of the CATALOG listing) so that
you don't try to read beyond the end of the file with the last segment. 
Not sure what happens if you try...I'm new to ProDOS.
