I have the following problem that I need help with. I have a module with the following function in it: 
sub GetSSNameFromFile( $\$\$ )
{
   my $s_InputFile = $_[ 0 ];
   my $rs_OutputFile = $_[ 1 ];
   my $rs_RecurseLabel = $_[ 2 ];
   my $s_SSDataDir = "$ENV{ SSDIR }\\data";

   ++$$rs_RecurseLabel;
...

[download]
It is called with the following code: 
GetSSNameFromFile( $sFile, $sRealName, $sRecurseLabel );

[download]
where all parameters passed in are standard my scalars. When I run the code, I get the following error: 
Modification of a read-only value attempted at D:\dlkusters\vsstools\v
+sstools/VSS/Utils.pm line 102.

The line specified is the unary increment on $rs_RecurseLabel. What exactly is a read-only value in perl and why is $rs_RecurseLabel one? What am I doing wrong and how do I fix it?

I bow at the monastery alter for guidance...
