Specifying output data file location?

[David McFarlane]

Hmm, on further thought (without benefit of getting StartupInfo files to 
work yet myself) I think that, in order to have each student's data 
files go into a separate directory, you would still need to give each 
student their own copy of the experiment program along with a mated 
StartupInfo file.  This still seems rather clumsy -- among other things 
every time you revised the experiment program you would have to redo all 
the copies for each student, and you could accomplish much the same end 
without StartupInfo files just by giving each student their own 
directory containing their own copy of the experiment program.  So I 
might have to retract a bit of my earlier enthusiasm for the StartupInfo 
file mechansism.

(BTW, the "New Features Guide" that went out with EP2.0.8.73 has the 
wrong figure for section 1.6.2.1 about the StartupInfo Editor.  Matt at 
PST kindly sent me his original (and correct) version of that section, 
and I posted that at http://www.pstnet.com/forum/Topic4015-6-1.aspx for 
everyone.)

But now the good news -- I totally cracked this longstanding problem! 
(Or did I just fail to do a proper search of the archive?).  It's not 
even that hard, and we had the clues all along in the code that E-Studio 
generates for the Main() routine.  I will post my solution in a separate 
thread with a title like "How to use a custom data file or path name."
