can I use here doc with variables? IE: 
$var=<<"EndOfText";
g
s
d
regkngljkasn
EndOfText
print $var;

    To make it explicit: Here-docs are simply strings with a special quoting style. They can be used anywhere you would use a string.

      Well, one thing about them that might catch some by surprise is that a here-doc comes in two pieces and those two pieces can end up pretty far apart. Take an example: 

      print <<FOO, <<'BAR';
Usage: $0 [arguments]
FOO
This program doesn't do much.
BAR

      If here-docs were just like strings and didn't come in two parts, then you'd want to write that more like: 
      print <<FOO
Usage: $0 [arguments]
FOO, <<'BAR'
This program doesn't do much.
BAR;

      [download]
      which doesn't work. You can write it like this: 
      print <<FOO
Usage: $0 [arguments]
FOO
, <<'BAR'
This program doesn't do much.
BAR
;

      but I think the first example is easier to read.

    Yep,

    That worked when you tried it, right?
[reply]
      no it didnt work. sorry
[reply]
        Are you sure? I typed "perl" on the command line, pasted your script example in, executed it and it printed what it should have done.

        Could you let us know what happens when you try and run the code?
