Look: forgetting the limited example you're showing, you are probably in one of two situations...

1) List is a native cursor in which case there isn't any reason why the original column in the cursor can't be M rather than C as Peter showed you

2) List comes from somewhere else, a query from some external source, in which case you can do something like the following to ensure the correct results:

DBSETPROP('List.a','FIELD','DataType','M')

or

CURSORSETPROP("UseMemoSize",1)

... right? What am I missing?
