Hi,

is it by design, that the following lines give the same result?




I thought expressions have always to use % if not only variables are allowed.

They will not give the same results. This is because the first one which starts with a % is an expression so it's like using a variable.
The second one will give you an error because Count in StringLeft needs to be a number, variable or expression (or else it becomes 0).

In StringLeft's count parameter, the help says, "The number of characters to extract, which can be an expression." Any parameter that is documented to be expression-capable doesn't need the percent+space prefix (however, you may include it if you wish).

Thanks for clarifying. I thought "... can be an expression" only tells, that expressions are *accepted* at this parameter. Maybe my bad english let me think this.
