Herman,
Did you really try the code [after the instructions] and didnīt work
reliably ?
Because it works in my 4.50.6.
If BEAS is #18 in the superWL60, it will give ID=18 in any
exploration [current stock, other WL including BEAS, other group
including BEAS etc].
This ID=18 will be unique for BEAS and, as far as I understood, it
was your request.
Do not forget to move **ALL** stocks into WL60 **BEFORE** any
exploration.
I have no doubt it works !!
