How to build my own SELECT-OPTIONS?

Question

Hi experts,
I hv 4 values like for a field, (say VBAK-BNAME),
NAME_A
NAME_D
NAME_M
NAME_Z
My selection- screen is like,
SELECT-OPTIONS: MANAGER FOR VBAK-BNAME.
So,
1) How to build the SELECT-OPTIONS table in my ABAP code?
I mean, if the user enters the NAME_A TO NAME_Z in select-options, the system shuld take in-between NAMEs also!
(Actually, I thiught that, the SAP will take care of building the select-options table based on Alphabetical Order, but, When I observed in debug mode, its not like that!)
2) And Where I hv to write the code for building select-options? I mean, Is it DATA DECLARATION part, AT SELECTION SCREEN or AT SELECTION SCREEN OUTPUT or START OF SELECTION?
thanq.

Hi,
Pls. suggest me other than RANGES?
Well, if you don't want to use RANGE then you can do it at SELECT statement.
SELECT BNAME
INTO TABLE ITAB
FROM VBAK
WHERE BNAME IN ( NAME_A, NAME_D, NAME_M, NAME_Z )
OR
SELECT BNAME
INTO TABLE ITAB
FROM VBAK
WHERE BNAME BETWEEN 'NAME_A' AND 'NAME_Z'.
2) under which event i hv to write it?
If you are using in SELECT statement, then you use at START-OF-SELECTION.
If you are buiding RANGE, then you can use at any events such as INITIALIZATION, AT SELECTION-SCREEN OUTPUT, START-OF-SELECTION, etc.
