Modifying $0?

[Davy Durham]

Hi,
  I apologize if this is the wrong list to ask, but it's the only list 
referenced on http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html

  I wanted to know if it's at all possible to change the value of $0.  
I'm executing bash where the first argument is the file I want it to 
read commands from.  But this is a temp filename and $0 contains this 
ugly temp filename rather than something better (I'd rather it contain 
the filename I created the temp file from)  These scripts are also 
sensitive about what file-descriptors are opened and are interactive, so 
I can't pipe the commands in via stdin reliably.

  I looked thru the manual to see if perhaps there was a different way 
of having $0 initially set to something besides this first argument, but 
since I'm not using the -c flag I can't.  And I tried combining using 
the first arg filename feature and -c .. but that didn't work either.

Thanks in advance,
 Davy
