If will execute the assignment statement, then perform the test.

Unlike a if statement it's a looping construct.

I don't know whether the while test will ever evaluate true more than
once through the loop.

@lines is used in pass1 and pass2 at least.

I agree that it could be a lexial variable on top-level, if that's
what you are sugggesting.

$in_pre is also used in
sub EnterIndexEntry

Perhaps it should become lexically bound and be passed as an argument,
as in
EnterIndexEntry(..., $in_pre);
