Command substitution failure - why?

[Vidiot]

I'm using zsh/

When I enter the following on the command line, I get the expected result:

	echo ann001.jpg | awk "{ print substr(\$0, 1, length(\$0) -7 ) }"

Expect result = ann

But, when I do this:

	OUT=`echo ann001.jpg | awk "{ print substr(\$0, 1, length(\$0) -7 ) }"`

I get back nothing.  The variable is empty.

Anyone have an idea as to why the aboce isn't working?

Thanks in advnace.
