In this example ypu create a property sheet that shows how you define the list and add entries with both simple values and with picklists:
Code for the Property Sheet Example
Copy and paste this code to a form and then compile and execute the form:

Property Sheet Notes
Assigning the Value
Note that when you are setting the value of the #Value column and the the data class of the entry is based on #PRIM_ALPH, #PRIM_NMBR or a numeric field, you must use the Text property of the component.
CHANGE field(#PROPERTY) to('''Salary''')
CHANGE field(#VALUE) to('#SALARY.TEXT')
ADD_ENTRY to_list(#PROP_1)
SET com(#prop_1.CurrentItem) dataclass(#salary)
Returning a Value
When you are returning a value from the property sheet, you must use the Value or Text properties of the data classes based on #PRIM_ALPH or #PRIM_NMBR:
USE builtin(MESSAGE_BOX_ADD) with_args('First name: ' #GIVENAME)
USE builtin(MESSAGE_BOX_ADD) with_args('Last name: ' #SURNAME)
USE builtin(MESSAGE_BOX_ADD) with_args('Salary: ' #SALARY)
USE builtin(MESSAGE_BOX_ADD) with_args('Alpha Options: ' #OPTIONSA.TEXT)
USE builtin(MESSAGE_BOX_ADD) with_args('Numeric Options: ' #OPTIONSN.TEXT)
