. . .
I was told that "predeclaring" the variables outside the loop saved
on memory allocation,
IIUC, all of those scratchpad variables are created on sub entry. The
performance difference of "predeclaring" is therefore zero.
and that using @rules instead of four named variables was also more
efficient.
In time or space? Time may depend on how many times you access them.
But names are always more meaningful than hardwired subscript indices.
