open IN, "a.txt";
while(<IN>) {
if ( ....next line awaited.... ) {
$_ = <IN>
........
........
}
}
close IN;
Reading from opened filehandle in the scalar context reads one line only.
$line = <IN>;
Reading from opened filehandle in the array context reads whole file (the
rest of th file).
@lines = <IN>;
