Hi Not sure where to begin in describing my problem so I'll start with the code 
open(INFILE, "iftoportchop");
    while(<INFILE>){
    @if2port = split /:/,$_;
    if ($if2port[0] =~ /([1-9]\.\d+)/){
        $numvar1 = $1;
            }
    open(INFILE2,"portnameok");
        LINE2:    while(<INFILE2>){
        @pnamok = split /:/,$_;
        if ($pnamok[0] =~ /([1-9]\.\d+)/){
               $numvar2 = $1;
        next LINE2 if $numvar2 > $numvar1;
        if ($numvar1 eq $numvar2){
        open(OUTFILE4, ">> swapnum");
        s/$pnamok[0]/$if2port[2]/;
        print OUTFILE4;
            }
        }
       }
}

The above works and I end up with the values swapped, however when the values are swapped a "carriage return" is inserted so the final output ends up spread across two lines, I of course need it to be on one line. Here is an example of my source data. 
"iftoportchop"
.portIfIndex.3.1 : INTEGER: 377

"portnameok"
.portName.3.1 : DISPLAY STRING- (ascii):  HX06S24E-CHASSIS1

Below is a sample of the output that I get 
377
: DISPLAY STRING- (ascii):  HX06S24E-CHASSIS1

Whilst looking though Q&A I found a reference to 
$var =~ tr/\n/ /;

But this has the effect of removing all of the hard returns, which is not what I want. Any Ideas on resolving this problem will be most appreciated. Thanks
