'How to use a runtime variable in FitNesse

Let's say I have the following FitNesse page:

!| com.myproject.fitnesse.fixtures.SSHFixture |
| set host | ${hostSi1} |
| set port | ${port} |
| set user | ${user}  |
| connect |
| show | run command | pwd |
| disconnect |
www.<variable>.com

The page contains one table and a link. The table will execute the console command pwd. How do I save the result of that command in a FitNesse Variable? I want then to use the variable within the same page. For example in the mentioned link.

Some resources are mentioning SLIM style, but I have no idea how to accomplish that in my case: Using data from fitnesse table as a variable
