That part of it worked, see test/islocal.awk. + +However, it's not complete. As Andrew Schorr pointed out, +this program did not work: + + function foo(x) { + print islocal(x) + x = 1 + print islocal(x) + x++ + print islocal(x) + } + + BEGIN { + foo() + } + +As this feature wasn't seen to be very compelling, and making it +work well would be too much work, this branch is being abandoned. + +Arnold Robbins +arnold@skeeve.com |
