Simple condition.

If there is no need to execute alternative code branches and the expression to be executed can be written in one line, you can use a single-line notation:

If <condition 1> Then ...

You can use any valid expressions in conditions that evaluate to true or false. A string equal to «1» is taken as true, «0» or an empty string is taken as false.
