I've seen shops replace the GOTO's with the equally nasty CAB
'A' CABEQ 'A' TAGSTM
But, hey, no explicit GOTO's!
I guess what they are saying is that you can still use GOTO, but you have
to break out of free format to do so.

Please respond to

GOTOs cannot be universally removed unless you substitute a new variable -
this is not my opinion, it is provable fact. I don't really care about the
new variable per se but it means that old code containing GOTOs cannot be
automatically migrated to the new format - someone has to manually go in
and
either make the change or, at least, review the work of a tool. GOTOs can
be pernicious but if you remove them from the language, you have to do more
work to use the new language spec. I personally think that they should be
left in. There are things that GOTO does better than anything else. If
someone else is afflicted with bad GOTO programming, it is not so much the
fault of the statement as the fault of the design or "the eye of the
beholder".
