sfeam, Hans-Bernhard Br\"oker, thank you for your replies.

It might be that I should provide you with more details.

So I have two files:
"sprintf.txt"
0.2	1.5970E-01	1.1262E-01
0.4	5.7188E-01	2.2227E-01
0.6	2.2019E-01	4.3648E-01

and a script file called "plot_sprintf" that I execute the following
way "./plot_sprintf 20 1"
#!/bin/sh
gnuplot << EOF
set terminal postscript eps enhanced
set output 'plot_sprintf.eps'
plot "sprintf.txt" using (\$1):(\$2) w l ls 1 t sprintf('T > %03.0f
abc',$1),\
     "sprintf.txt" using (\$1):(\$3) w l ls 2 t sprintf('T > %3d  abc',
$2)
unset table
EOF

As a result I get an file called "plot_sprintf.eps" that contains the
following lines "T > 020 abc" and "T > 1 abc" (instead of "T >   1
abc" I want).

P.S.
I would have attached the eps file, but I don't know how to do it?
Should I upload it to some website and post a link here?
