I use an equivalent function, provided by the framework - and I find it very useful.

The framework itself often uses it to pass several parameters as a single parameter.

I think the reason that the framework creates a substitute is due to the handling of empty parameters:

"par1;par2;;par4"

GetWordNum(..., 3) would return "par4", due to the definition of empty space. (The semicolon is the default delimiter in the framework.)

Hilmar.

which clearly save lots of coding and does not distract you from more important programming lines.
