Ah, but I wasn't suggesting that.  I was thinking of using xargs to invoke 
gawk with one long argument, instead of passing it on the command line...  
However, now that I think of it, that's probably no different than running 
it from the shell...  Oh, well...  I guess Hans's solution with mktemp is 
the best under the circumstances.
