In your test, how many records in imsfilter? How many records are selected into cursor? Try with one record in imsfilter and post result returned by SYS(3054) in each case.

LOCAL cmemvar
=SYS(3054,11,"cmemvar")
SELECT ...
_CLIPTEXT = cmemvar

>>You can try

>>* JOIN
>>SELECT cr.plot_id ;
>>	FROM crzplots cr ;
>>	JOIN  imsfilter ON linkfield = cr.plot_id ;
>>	INTO CURSOR cPlots
>>
>>* Correlated subquery
>>SELECT plot_id ;
>>	FROM crzplots ;
>>	WHERE EXISTS (SELECT *  FROM imsfilter WHERE linkfield = plot_id) ;
>>	INTO CURSOR cPlots

>Tried both. Both still return SYS(3054) of "none" for both tables.
