Here's what you have:
$processor = `/aa/bin/get_bind_cpus.ksh`;
This will leave $processor with a value like "1\n" (that's the numeral 'one', and a newline). What you want is to have a reference to a number '1'.
So I say cast $processor as a number with 0+ to get rid of the newline, and then make it a reference.
$processor = 0+ `/aa/bin/get_bind_cpus.ksh`; $processor = \$processor;
You can do this all in one step like so:
$processor = \( 0+ `/aa/bin/get_bind_cpus.ksh` );
Note that this means if `/aa/bin/get_bind_cpus.ksh` outputs some nonsense, that will be interpreted as zero. If you want to be prepared for that, you'll have to validate that somewhere.
