perl pack and unpack commands

I have a file that contains user id and corresponding password.
Lets say password is "help". The below command will create a hex value for string "help".
perl -e 'print unpack "H*","help"'

So now password is in encoded format.

Then I decoded it in the script where am fetching the password.

perl -e 'print pack "H*","77636462614e3031"'

Now you help is required. In the second step when I am passing the hardcoded value, then it is able to decode it.
But when I am using a variable it is not working.

ex: var="77636462614e3031"
perl -e 'print pack "H*",$var'

This doesn't work. Let me know the syntax so that it will return correct value when I use it in a variable?
I am trying to execute this perl commands in LINUX OS.

Please help.

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME

       extract_font_range - Extracts a range of characters from a font. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       FONT *extract_font_range(FONT *f, int begin, int end)

DESCRIPTION

       This  function  extracts  a  character range from a font and returns a new font that contains only the range of characters selected by this
       function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or  to  the  end  of  the
       font.  Example:

	  FONT *myfont;
	  FONT *capitals;
	  FONT *fontcopy;
	  ...
	  /* Create a font of only capital letters */
	  capitals = extract_font_range(myfont, 'A', 'Z');

	  /* Create a copy of the font */
	  fontcopy = extract_font_range(myfont, -1, -1);
	  ...
	  destroy_font(capitals);
	  destroy_font(fontcopy);

RETURN VALUE

       Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
       to avoid memory leaks.
