I'm attempting to "split" a multi-line string into a string of a specific length. The length of the original string is variable. The first thing that I thought of is using a combo of substr and s/// to do this.

For some reason though, the below goes into an infinite loop. Can anybody explain why? Point me towards a better solution (non-modular, I know all about Text::Autoformat). 
$description =~ s/^(\s+)?$//g;   #get rid of blank lines
$description =~ s/\n/ /g;        #get rid of new lines
while ($description)
{
    my $temp = substr($description,0,75);  #get first 75
    $description =~ s/$temp//;             #strip the 75
    $f_desc .= "T" . $temp . "\n";         #put a newline at the end
}   
#when the loop is done, $f_desc should hold the parsed description
