open file for read and append

Hello, I have a script where I need to open a file, read from it sequentially, and append items to the file as I go along, continuing to read these items as I go. But seems I can't open the file for read and append at the same time. Does anyone have any ideas? Many thanks. -- Daniel Klose PhD

Variables in replace regex

Hey all... I want to use groupings, (TEST), and replacement variables, $1, $2, etc, in a replacement regex, but the replacement is built into a variable. Like so: #!/usr/bin/perl my $replace = "urgent \$1"; my $string = "This is a TEST"; $string = s/(TEST)/$replace/gi; print $string; It outputs
