I wouldn't recommend that, since the tabling operation
only preserves some of the information in the original
input stream.  Much better is to use the version 5
"Here Document" method:


$DATA_1 << EOD
1 2 3 # first line of data
3 4 5 8 9 
EOD

$DATA_2 << EOD
5 6 7
8 9 0
EOD

plot $DATA_1 using 1:2, $DATA_1 using 1:3, $DATA_2
