How to pass select options range value to another program?

I need to submit program #2 from my program #1, I have no problem passing Parameter since they are single value. But when I pass the select-option data, let say company code 1000 to 2000, then the data range is incorrect.

I remember I have to assign the Sign and Option to the input value range.

Can someone give me an example code of how to define the Select Option field in program #2.

Thanks.
