Then it's exactly what the standard tr or sed can do.

It does; however, you have to run pipe-enabled gnuplot, i.e. gnuplot.exe or 
wgnuplot_pipes.exe (see README.Windows).

You can read all of them at once; and then use words() and word() functions 
to step through the file list, e.g.

if (!exist('a')) a=system('dir *.dat | bksl2sl'); n=words(a); k=1
plot word(a,k)
pause 2
k=k+1
if (k<=n) reread
