loopy question

[Wright, Thomas]

Folks,


A questions about loops and files.

If I have the following construct:

while (<FILEA>) {
  $recA = $_
  do something;

    while (<FILEB>) {
       $recB = $_;
       if ($this) {
         do something2;
       } elsif ($that) {
           do something3;
           last;
         } else {      # the other
             do something4;
             last;
           }
     }

  do something5;
}




When the inner loop is exited, the outer loop continues, then it reenters
the inner loop again.

opening and closing the files takes place outside of both loops.


Question(s?): Will the position in FILEB be held so that reading data from
it will pick up where it was left off when exiting the inner loop
previously?
If not, what happens/where will it be? (implicit close/reopen?)

( I know, I would rather use an array, but the file is too large to load
into memory).



Thanks,
Tom Wright
