I have not used the Continue or Break control structure very often, probably
because I was taught that methods, functions, loops, etc should have one exit
(whenever possible). That is kind of like the "Third Normal form" in relational
theory - nice idea but sometimes not practical.
The other reason is that I seem to have periodic problem with it in for each
loops. I can't pin down the exact circumstances but something like:
$c := new collection("one";1;"two";2;"three";3;"four";4)
for each ($c; $key; $value)
if ($value = 3)
continue
end if
writebr('$key $value')
end for each
will SOMETIMES generate a syntax error
continueend if
Syntax error.
Continue is on a line by itself but the parser seems to miss that. The instance
I'm dealing with is in a private library method called from a loop in a library
method. I've tried to simulate that with the above test code, but it works
fine. Unfortunately I had to resort to some deeply nested if statements.
Just wondering if anyone else has encountered this and know what the
circumstances are. This is active4d 4.5.
