gnuplot redirect data to a here-doc

This command works properly to write the results to the file "oneMonthDataOnlyfile.txt"

system("/usr/bin/sed -e '1,3d' " . "oneMonthData.txt" ." > oneMonthDataOnly.txt" );


Can I do the redirect to a here-doc, e.g.:

system("/usr/bin/sed -e '1,3d' " . "oneMonthData.txt" . "> $myData);


When I try with the above formatting I get "parenthesis expected"

or withsystem("/usr/bin/sed -e '1,3d' " . "oneMonthData.txt" ." > $myData " );
sh: $myData: ambiguous redirect
ambiguous redirect

system("/usr/bin/sed -e '1,3d' " . "oneMonthData.txt" ." > $myData " );

or: system("/usr/bin/sed -e '1,3d' " . "oneMonthData.txt" > $myData);
throws: "Column number or datablock line expected

system("/usr/bin/sed -e '1,3d' " . "oneMonthData.txt" > $myData);

Am I getting the formatting wrong or can a here-doc not be populated this way?

Try this:

set print $myData
print system("whatever command you like")
unset print
