Re: do-until: Can't "next" outside a loop block.

in reply to do-until: Can't "next" outside a loop block.

Hi humble,

if you check do documentation, you will notice this:
"do BLOCK" does *not* count as a loop, so the loop control statements "next", "last", or "redo" cannot be used to leave or restart the block.
check this perlsyn for alternative strategies.

However, If you must use the do as stated in your code with next, then you have to "double" the braces like so:

do{{ next .... }} until ...;
Please see perlsyn for more.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
