LIST = hid::get( �LIST� )
An array (A) in AWK can represent a list of unique items with an undefined order.
To introduce the concept of an array with a defined sequence of its indexes (items),
we need to specify this sequence in a subarray A[LIST] as a simple list.
# items of A: first, next and last:
A[ �LIST� ][ �� ] = �first�
[ �first� ] = �next�
[ �next� ] = �last�
[ �last� [ = ��
[ �first� ]...
[ �next� ]...
[ �last� ]...
Thus, instead of a for-in loop for array A, we use:
i = ��
while ( �� != i = A[ LIST][ i ] )
# process A[ i ]
or
for ( i = ��; �� != i = A[ LIST ][ i ]; )
# process A[ i ]
At the same time, we can still work with the main array in a for-in loop � with one caveat:
for ( i in A )
if ( i in HID )
continue # this is hid (LIST)
else
# process A[ i ]
