Can you explain a few things I don't understand?
- First thing I don't understand is this way of making
subs (sub'i, sub'p, sub'f) what's the main difference
from the sub i{..}.
- Second, in this line : \;$m.="$/$/$/$/$/$/1; I don't
really get what you are doing there.
- Third, $/$/$/$/$/$/$/";; why ;;?
