Were I to guess you're running W32:

#!/usr/bin/perl

print "Success Ran Here";

=head

path\to\success>perl -e "@var=`success.pl`;print @var;\n"
Success Ran Here
path\to\success>

path\to\success>perl -e "@var=system(\"success.pl\") or die \"can\'t r
+un\";print \"@var \n\";"
Success Ran Here0

path\to\success>
    # the "0" is errno from system ie, no error;
    # were you executing this from the same dir as holds "success.pl"?

path\to\success>perl -e "@var=exec(\"success.pl\") or die \"can\'t run
+\";print \"@var \n\";"
    and...
path\to\success>perl -e "@var=exec (\"perl success.pl\") or die \"can\
+'t run\n\";print \"@var \n\";"

path\to\success>Success     
   # note the blank line before the last prompt, and the location of t
+he word "success"
   # perldoc -f exec:  The "exec" function executes a system command a
+nd never returns* 
   # If your OS (windoze?) does not have perl associated with .pl, thi
+s won't work, and even if it does, IIRC, using "exec" won't assign an
+ything to $var usefully, as "never returns" means everything after th
+e "exec(..." won't be executed. In effect, the "exec(..." is like "ex
+it;"

path\to\success>perl success.pl  # ie, this file
Success Ran Here
path\to\success>

=cut

open(FH, "success.pl");
@var=<FH>;
close(FH);
print $var;

and if I guess *nix (as I do from the "-1" in OP's example 2):

ww@GIG:~/pl_test$ perl -e '@var=`success.pl`;print @var;\n;'
wheelerw@GIG:~/pl_test$

# nada (addressed in a prior reply)

ww@GIG:~/pl_test$ perl -e '@var=system("success.pl") or die "cant run"
+; print "@var \n";'
-1
ww@GIG:~/pl_test$

# system error; see reply above

ww@GIG:~/pl_test$ perl -e '@var=`success.pl`;print "@var\n";'

ww@GIG:~/pl_test$

# note blank line between prompts

ww@GIG:~/pl_test$ perl success.pl
Success Ran Here
ww@GIG:~/pl_test$

# newline added in 'print $var . "\n";' in *nix script

Oh yes, this summary is quite late. Thank the alarm that sent us running to a "odor of gas in a structure" call... :-)
