Hi,

I am using Rcs version control in my code.
I am doing check out operation for building version based filter.
User will select particular version from my dropdown menu .
Based on user selected version,I will use checkout "co" command in my code internally,to retrive the file based on version selected by user,i use

my version="1.4";
my $rcs = Rcs->new;
$rcs->co('-r $version');
or
$rcs->co('-r$version');
[download]

But i am getting error as

co: /auto/data/Test/TestCase/public/TC11544.xml,v: improper revision n
+umber:  $version
[download]

but when i give

$rcs->co('-r1.4');
[download]

i am getting expected output.Returning 1 as output ie success operation.
But i need to pass as $version only.
$version depends on user selection from drop down menu.
so i need to pass as $rcs->co('-r $version'); only.
I also tried following methods but its not working.

my $verfile=`co -r$version`;
$rcs->co("-r" => "$version");
my $verfile=`co -r $version`;
[download]

But i am getting error as

co: /auto/data/Test/TestCase/public/TC11544.xml,v: improper revision n
+umber:  $version
[download]

or as

co: RCS/1.4,v: No such file or directory
[download]

Could Some one help me in this regard. What i need to modify to get my code to work. Thanks,
Srins.
