Hi Arnold,
C predates the Bourne shell by several years.
Yes, but C was evolving. As it aged and spread in use, I agree it could
change less easily.
after a stint in Java with its multilevel break...
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. 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?
