I have a lookup table of values and formulae, that I reuse many times, like so:

    my (%frame_lookup_by) = (
        21 => {
            desc => "S/W Status",
            value => sub { $minor_frame_data[0]*256 + $minor_frame_dat
+a[1]} ,        
        }, 
        33 => {
            desc => "HK Subcom",
            value => sub { $minor_frame_data[1] % 16 } ,         #modu
+lo 16 of w12
        },
        117 => {
            desc => "General Status",
            value => sub {$minor_frame_data[0]*256 + $minor_frame_data
+[1] },        
        },
        129 => {
            desc => "Sensor Status",
            value => sub {$minor_frame_data[0]*256 + $minor_frame_data
+[1] },        
        },
    );

However, this hash is used by various subroutines, and @minor_frame_data varies with each time subroutine call. Is there a way to define this once and pass it into each subroutine, where it's updated as necessary? I'd like to avoid globals, obviously, but realize that if I declare 
my @minor_frame_data

[download]
in each subroutine, the @minor_frame_data in the has of subroutines and the current subroutine are in different lexical scopes, and thus contain different values. I want the values calculated in each subroutine to be derived from the current values in @minor_frame_data. In other words, the following

$ref_frame_lookup_by->{21}->{value}->()

[download]
should yield 257 if @minor_data = (1,1). Similarly, 

$ref_frame_lookup_by->{33}->{value}->()

[download]
should yield 1 if @minor_data = (1,1).

How can I write it so the @minor_frame_data values from the current subroutine are used instead of the ones in the original lexical scope?
