hi, while working on a script to automize Clearcase labelling I came across a weird problem. while running this code:

#perl -w

use strict;

my $view;
my $labelold;
my $labelnew;
my $ab;
my $ba;
my $element;
my $rc;
my $path;
my $path2;
my $input;
my $comment;

my @VOBs;
my @lijst;

#system("cls");
print "\nThis script will apply a label to all objects of another labe
+l.";
print "\nplease enter the name of the active view (e.g.: u12345-1): ";
chomp ($view = <STDIN>);
while(){
    print "\nEnter the name of a VOB you want to access (e.g.: PowerCe
+nter, PowerCenter_s), press Enter when finished:";
    chomp ($ab = <STDIN>);
    unless($ab){last;}
    push(@VOBs, $ab);
}

print "\nGive the name of the old label (e.g.: DXOPRJ0-1.0.0): ";
chomp($labelold = <STDIN>);

print "\nGive the name of the new label (e.g.: DXOPRJ0-1.0.1): ";
chomp($labelnew = <STDIN>);

print "\n Give the comment for the new label: ";
chomp($comment =<STDIN>);

$path = "u:\\$view\\";
chdir($path);
foreach $element(@VOBs){
    $path2 = $path . "\\$element";
    chdir($path2);
    $ab = "cleartool mklbtype -c \"$comment\" $labelnew";
    $rc = system "$ab";
    while($rc!=0){
        $rc = 0;
        print "\nlabel $labelnew already existed! Do you want to repla
+ce it(y\/n)?";
        chomp($input = <STDIN>);
        unless($input eq 'n'||$input eq 'no'||$input eq 'N'||$input eq
+ 'NO'){
            $ba = "cleartool rmtype –rmall lbtype:$labelnew";
            #121#print "$ba";
            $rc = system("$ba");
            if($rc!=0){print "\ndeletion of CC label failed!";}
            $rc = system "$ab";
        }
    }
    chdir($path);
    $ab = "cleartool find $element -version \"lbtype($labelold)\" -exe
+c \"cleartool mklabel -replace $labelnew %CLEARCASE_XPN%\"";
    $rc = system "$ab";
    if($rc!=0){
        die "\nan error occured...";
    }
    else{
    print "\nlabelling $element succesfull!";}
}

the print statement #121# returns "cleartool rmtype ūrmall lbtype:LABEL" instead of "cleartool rmtype -rmall lbtype:LABEL" this of course results in an error with the system call. I tried to use backticks, but the same problem occurs. When skipping this option the program gives the correct result. To test the nature of this problem I made a quick program with only the print statement:

#perl -w
use strict;
print "cleartool rmtype -rmall lbtype:LABEL";

This returns the correct output. At this point I was lost. Does someone know what causes this problem and how to solve it?
