There's still a limit imposed on the length of the string, for example:

=CursorSetProp('UpdateNameList', lcFieldString, 'MyTable')

If lcFieldString is greater than 255 characters then this command will not work correctly, i.e. the table fields will not update. If lcFieldString is less than 255 characters the table fields update correctly. In neither of these instances will VFP return an error.

If I use substitution to replace lcFieldString, i.e.:

=CursorSetProp('UpdateNameList', &lcFieldString, lcParam1)

VFP returns an error saying "Contains unrecognised keyword/phrase"
