Format loop variable in gnuplot

I want to loop over the files basename0.00.txt, basename0.01.txt, ..., basename1.00.txt.

Doing this doesn't work:

plot for [t = 0:1:0.01] 'basename'.t.'.txt'

Because t is 0, not 0.00. I need to format it. How to go about this? I've tried using:

`sprintf("%3f", t)`

But I get:

sh: 1: Syntax error: word unexpected (expecting ")")

Are the backticks supposed to be there? Otherwise I get invalid command.

gnuplot --version
# gnuplot 4.4 patchlevel 3

You can iterate only over integers:

plot for [i=0:100] sprintf('basename%.2f.txt', i/100.0)

That works fine with 4.4.4
