Hi, I've written two methods printR and printL to write text on the right side and left side respectively on the screen. It's working fine.

sub printL { my $str = shift; my $widthL = 60; #my $widthR = 80; my @strWrap = (); for (1 .. int (length $str)/$widthL ) { push @strWrap, substr($str, 0, $widthL-1, '')."\n"; } #push @strWrap, $str; print "@strWrap"; printf ("%-80s", "$str"); } sub printR { if (@_ == 1){ my $status = shift; print "$status\n"; } elsif (@_ == 2){ my $status = shift; my $msg = shift; print "$status\n$msg\n"; } }

Now there is one problem. In my code I've used multiple printL methods consecutively. So first printL writes at the left side of the screen and leaves the cursor at that place only and next consecutive printL continues from there. that's not what I want.

I have a solution for this. I can find the current cursor coordinates and if x coordinate is greater than 0, next printL will add newline char at the beginning of the string. But, how to find current cursor position, I don't know. Can somebody help me with this?

Perl tell function doesn't help me with this as it returns the position in bytes. Any suggestion would also fine.
