zentara, thanks for yet another great worker thread example. ++. I'm pretty sure you know the techniques I use below. I hope that my alternate, goto-less approach is useful to someone.
It's possible to get rid of the gotos. I don't know that it improves readability/maintainability. I like the way that the gotos work to jump out of the loop in the original.
On with the code. Removing the first goto:
I used last to break out of the loop. I added a label to retain the readability of the goto version. It's functionally equivalent to the goto version.
Now the second and third goto:
I wrapped the section bracketed by the START label and goto START with a loop. I didn't label the loop, because we never break it. It may make sense to apply a label here in some instances.
I added a label to the pre-existing loop (now an inner loop), and use last to break out of it as needed. Once again, to improve readability, I used a label where it isn't necessary.
Whether these changes are worth making, I can't say for sure. I tend to prefer the inner/outer loop arrangement I show above to zentara's loop implemented as a goto, simply because I can bounce between the enclosing brackets with my % key. I like the other gotos, and feel that they do help readability. YMMV.
