Yes, it does matter. L3P/L3Lab give you a warning
SKIPPING "a.mpd" Line 4: FILE b.dat already read: 0 FILE B.DAT
and 'some stuff' gets treated as part of file A.DAT.
So here 'some other stuff' and 'some stuff' get drawn.

Right, my concern was the ability to compose a Datsville DAT file with
references to many MPD files submitted by contributors.
It should be OK for two authors to use the same subfile name,
e.g. "roof" in my example: http://news.lugnet.com/cad/dev/?n=4188
