I am new to tcl scripting and I am having a really hard time understanding how to execute a tcl script. I have the project open in quartus and the tcl script in the same directory as the project.
The scripts does virtual pin assignments and I took it as it was from the altera website.

Tcl scripts can be 'sourced' from a Tcl shell.
In the Quartus GUI, click on the Tcl shell. If you can't see the shell, make it visible using View->Utility Windows->Tcl Console.
Then at the Tcl prompt (which looks like tcl>) type:
tcl> source my_script.tcl
where my_script.tcl is the script you are trying to 'execute'. What you are really doing by sourcing the script is saving yourself some typing. If the script defines a procedure, eg., something like this
proc boring {} {
puts "This is a boring procedure!"
}
Then it defines a new procedure in the Tcl shell. You can then type
tcl> boring
and the shell will run the procedure, which prints a message to the console.
If you want to see more complex use of Tcl scripts, go through this tutorial:
