I'm working with Progress-4GL, release 11.6.

I'm trying to initialise a SELECTION-LIST, but not with LIST-ITEMS, but with LIST-ITEM-PAIRS.

In order to initialise with LIST-ITEMS, I needed to do the following:

Code:
sl-SELECTION_LIST:LIST-ITEMS = "".

When I try this, for LIST-ITEM-PAIRS, this seems not to work:

Code:
sl-SELECTION_LIST:LIST-ITEM-PAIRS = "".

This gives the error that the number of entries must be even.

Code:
sl-SELECTION_LIST:LIST-ITEM-PAIRS = ",".

This puts an empty line as the first entry of the SELECTION-LIST.

Does anybody know how to do this?
Thanks in advance
