switch/case in awk

[superstarjpmc]

Hi,

I came to know that switch/case is a feature only in gawk.

What can be the equivalent of switch/case in 'awk' ?

Any efficient construct to mock switch/case in awk ?

thanks
david

I use do-while:
[tt]
BEGIN{
x = 3
do {
if (2==x) { print "double"; break }
if (3==x) { print "triple"; break }
if (4==x) { print "quadruple"; break }
# default
print "unknown"
} while (0)

}
