The refinement <#45#>program<#45#> has, by the reading, obtained a value, which can be displayed on the screen by means of the show-command
The focus is still <#48#>program<#48#>, but now its meaning is defined,

We can execute the program with this refinement as root
by giving the execute-command
Just try it, and see what happens.
