Command Prompt for environment URL

Hi All,

We are using Silk Test Classic 16.5.  We have to run our tests in multiple environments.  We are wondering if there is a way that we can create a command prompt in SilkTest to ask the tester to enter the Environment URL, User Name and Password etc before running it from test plan.  Currently we are hard-coding these information in the script file as global variables.

Thank you for any input!
