Probably the best discussions on this topic were published in
	ACM Computing Surveys
	Vol 6, No 4, December 1974
If you have access to a CS library, go look up this volume.  In one
paper, Niklaus Wirth shows why goto's are unnecessary, and in another
Donald Knuth shows why "absolutely no goto's" is a needlessly harsh
dictum.

I strongly recommend that anyone tempted to comment on goto usage
read these papers first.  (They total more than 50 6"x9" pages.
I cannot provide copies, so please don't ask.)
