At the level of the reference manual, the only change to the language
I could find is the scope of a goto. It now says:
A label is visible in the entire block where it is defined, except
inside nested blocks where a label with the same name is defined and
inside nested functions. A goto may jump to any visible label as long
as it does not enter into the scope of a local variable.
As I read it,
for i=1,n
if a[i,i]==0 then goto continue end
for j=i+1,n
if a[i,j]==0 then goto continue end
eliminate(a,i,j)
::continue:: end
::continue:: end
will now do mimic the continue statement.
How's that arm doing, Steve? :-)
