Hi Arnold,
Yes, since you have to keep track of a label in a table somewhere that
you can look up.
Oh, I think our wires are crossed.
I wrote:
Remember too that the C compiler had to fit in a small
space;
having multilevel or labelled breaks requires more bookkeeping.
Is it more bookkeeping than is already needed to handle the ends of
the nested for-loops, say?
Given sh(1)'s break takes an optional number of
loops to break out of,
I'm surprised C stuck with just the single-level break.
In other words, ‘break 2’ works in sh but not in C.
You added labelled breaks; I wasn't asking if they upped the
housekeeping, just ‘break 2’.
