Ya know, I gotta disagree... and this is coming from a
programmer
who made liberal use of the GOTO statement.
...
Not that I look down on programmers who use it, not in
the least.
But for me, I'm fairly happy it's less common nowdays.
Programming mostly in assembler I couldn't avoid GOTO, relative or
absolute, if I wanted to so it's fortunate that I don't. Computed
GOTOs are not only 'not a bad thing' they are a very usefull tool at
this level, condensing long lists of compares to a simple calculation
and table.
To proscribe the use of any particular construct within a language
wastes effort when that constuct could provide a solution, it's up
to the programmer to use all of a language appropriately.

I don't know of any compiler that doesn't throw in jumps all over the place.
Goto's can be bad if they make the code hard to follow but I find that most
people write such sloppy code that it's hard to follow anyway as well as
making code more complicated trying to avoid goto's.
I rarely use goto's unless I am programming in assembler, I am not sure
about my motives probably just because of peer pressure.
With most languages goto's can still be clear about what is happening, my
pet peeve is a call followed by a return, a goto is just as clear and it is
faster.

'goto' is still very much alive : only they call it throwing an exception
these days.

Disgaree.
if (index(s,'/'))
{
... process ...
if (! index(s,'*'))
{
... compute new pointer and store it in is ...
goto no_slash_after_all;
}
} else {
... process ...
no_slash_after_all:
... more processing ...
}
A certain kind of goto usage turns into throwing an exception, perhaps.
But that doesn't mean that goto is alive and well, any more than some
uses of punched cards being replacable with magnetic disks means that
punched cards are alive and well.
