As previously noted, /^JRECOV="yes"/ && /^TEOJ="-w"/ is no good.

The desired condition is "Were JRECOV and TEOJ seen in the file?" Notice the past tense. The "and" needs to be done at the end of the file.

while (<>) {
   if ($seen) { $seen = 1; print "$ARGV: "; }
   $JRECOV = 1 if /^JRECOV="yes"/;
   $TEOJ   = 1 if /^TEOJ="-w"/;
   if (eof) { # Not eof()!
      print $JRECOV && $TEOJ ? "yes" : "no", "\n";
      $seen   = 0;
      $JRECOV = 0;
      $TEOJ   = 0;
   }
}
