Michael,
vResponse is the variable which will hold the returned value

The DIALOG Lookup command appears to do what I would like it to do -- but the
documentation ends without any explanation of how to access the value selected
in a lookup. I see no new variable, or any that appear to hold the resulting
value. It appears to me that the value selected simply disappears into a black
hole.
I copied the example from the manual/help screen, changed my table & column
names, and it works on screen...just doesn't produce any resulting value I can
find or access. As an example, I'd like the user to examine a list of
customers, select one, and return the primary key value (CustID).
Using a POPUP_RETURN_COLUMN CustID | POPUP_RETURN_TYPE VALUE, where is the
value of CustID to be found?
If I instead use POPUP_RETURN_TYPE COLUMN, what info is actually returned? And
where is it to be found?
DIALOG 'Enter search string to look for in database' vResponse=25 vEndKey 1 +
CAPTION 'Search' ICON INFO + OPTION
DIALOG_EDIT_HINT 'Double-Click for a List of Contacts' +
|POPUP_ENABLED TRUE + |POPUP_DIALOG_TYPE LOOKUP +
|POPUP_TITLE_FONT_NAME VERDANA + |POPUP_TITLE_FONT_SIZE 10 +
|POPUP_TITLE_FONT_BOLD TRUE + |POPUP_TITLE_FONT_COLOR
GREEN + |POPUP_TITLE_BACK_COLOR WHITE +
|POPUP_TITLE_TEXT 'Select Contact to Edit' +
|POPUP_LIST_FONT_COLOR GREEN + |POPUP_LIST_BACK_COLOR WHITE +
|POPUP_CAPTION 'List of Citizens' + |POPUP_TABLE
Citizens + |POPUP_SELECT Name_F,Name_L, Addr1, Addr2, Email +
|POPUP_RETURN_COLUMN CitizenID + |POPUP_WHERE ORDER BY
Name_L, Name_F + |POPUP_SHOW_LINES TRUE +
|POPUP_RETURN_TYPE COLUMN + |POPUP_LINES 20 +
|POPUP_DISTINCT TRUE
(manual's example adapted to my data).
Thanks for any guidance.
