Not sure why you would want to do this, or what problem you're trying
to solve...
But, you could do something like this:

my %grprint_formats = (
	mem		=> {
		MAX		=> '%5.3lf %3bytes,
		MIN 	=> '%5.1lf %sbytes',
		AVERAGE	=> '%5.3lf %sbytes',
		LAST 	=> '%5.3lf %sbytes',
	},
	kernel	=> {
		MAX		=> '%5.1lf %sbytes',
		MIN		=> '%5.1lf %sbytes',
		AVERAGE => '%5.1lf %Sbytes',
		LAST 	=> '%5.1lf %Sbytes',
	},
);

Then to access individual items, you'd do something like:

print "$gprint_formats{mem}{MAX}\n";
etc..

You might find the PDSC useful - http://perldoc.perl.org/perldsc.html
