I want to set up a filter in the alert setup form for multiple call prefixes. I can't figure out the format and the wizard does not help either. I want the filter to catch a list. For example:

CALL=K5, K6, K7, W5, W6 ,W7, N5, N6, N7, VA, VE, U4

I've tried direct entry (CALL='K5','K6','K7') No good.
The wizard yields CALL='K5,K6,K7' for wizard entry K5,K6,K7 No good. Also tried spaces between. Still no good.
Tried 'K5','K6','K7'. Wizard yields CALL="'K5','K6','K7'" Yep still no good.

It does work with the following filter.

CALL='K5' OR CALL='K6' OR CALL='K7' OR CALL='W5' OR CALL='W6' OR CALL='W7' OR CALL='VA' OR CALL='VE' OR CALL='4U'

However, it would be easier to create filters for such things as CQ zone where many prefixes need to be filtered, if some sort of compounding were available.

Can anyone help?

G'Day Dave,

You need to comply with the "syntax" of the language in use - in this case Microsoft's Visual Foxpro. Search the Internet for the correct syntax.

You could use the "contains" operator. But you would need to create the test yourself, rather than use the filter's QBE. Click EDIT to modify the filter and change the test around.

That is

LEFT(CALL,2) $ "K5,K6,K7"

or

CQ_ZONE $ "30,31,32"

If you are so inclined you can write your own "user functions" to be executed by LOGic on your behalf. The sky is the limit.

See http://www.hosenose.com/forum/yaf_postst1130_Personal-function---spot-alerts.aspx
