in reply to print out keys of hash with carriage returns

One way is to set the output record field seperator, 

{
    local $, = "\n";
    print RPTOUT keys(%tapeid), "\n";
}

[download]
You could instead call join "\n", . . . on the keys.

Update: sth++, corrected.

    ...one minor correction, $, is output field serperator, $\ is output record serpperator.
