Hi,
using the "|" pipe character shouldn´t make any problems here, I also used this as separator in strings with no problems.
But from your code I am missing the assignment to the variable tempCommand. The variable is used as string containing the keyin command, but it is not assigned using cmd directly or parts from it
From your example I would expect the variable cmd should be used?
If this doesn´t explain the issue, could you please upload a full working example to allow us reproducing the issue.
Best regards,
Artur
