$var=<<VAR;
print "Blah";
VAR

print<<BLAH;
print "Blah";
eval $var;
BLAH

will that replace eval $var with "Blah"?

No, it will replace `$var` with the string `print "Blah";\n`, so when you run it you'll get `print "Blah"; eval print "Blah"; ;` [download] as your output, which is probably not what you want. See Masem's post and stephen's post below for how to do more interesting interpolation.

No, what you want is `$var=<<BLAH; print "Blah"; BLAH eval $var;` [download] Because when it executes it it will print Blah out on the screen because you have `print "Blah";` already inside $var; UPDATE:WOULD SOMEONE MIND TELLING ME WHAT IS SO WRONG ABOUT THIS POST THAT I GOT A -- ON IT??
