tcl script to run perl code and output the results?

Question

I need to run perl script through tcl script, but exec command in tcl is not generating the results of perl script.

tcl script (test.tcl) has following line

exec perl test.pl

perl script test.pl has following lines.

use strict;
use warnings;
print "Have a nice day!!!";

I am running tcl through cmd window as "tclsh test.tcl". No errors and no output. Why it is so???

exec command will return the output of the program and you have to capture it by saving it into a variable, or straightaway print it using puts.

set result [exec perl test.pl]
puts $result

However this code is not working when perl script generates a output file. Hence i used "exec perl test.pl" alone as code, but output file is not generated.

@SumathiGokul that sounds like quite a different question. Please ask a new one.
