Hi all, How do I pass integer array or text array as a parameter to the pro

Hi all,
How do I pass integer array or text array as a parameter to the process model.
When I pass in the input as 1,2,5 it shoots an exception for integer array.
It doesn't accept "a","b","c" as a text array.
How can this be achieved?
Any inputs are highly appreciated!!!!...
