Never mind, I found an answer, unless somebody has a better one. If you're curious:

afields( laFieldList, 'Table' )
if laFieldList[ rownumber, 18 ] > 0
    *autoincrementing
endif

>How can you programatically test if a field is autoincrementing? Can't seem to find any way to do it with DBGETPROP() or with CURSORGETPROP(). Any ideas? Thanks a lot,
