Erm, I don't think I saw any mention of replot anywhere in this
conversation.  It's quite counter-productive in for what you're doing 
here.  Among other things, it causes each data file to be gunzipped 
*three* times, instead of twice.

Check out 'help plot' to understand how to plot more than one data set 
in a single 'plot' command.  Modify pointsize by 'plot' option, rather 
than by 'set pointsize'.

But all of that is a side issue.  The real stumbling stone is this 
question:  which of the many programs used by this script: zsh, gnuplot, 
zcat or gnuplot, will evaluate the $4 in "{TIME=$4}", and all the other 
$<number> thingies further down the line?
