Subject Re: Encountered an improper argument From Bruce Beacham <bbeacham@no_plm_lowman.co.uk> Date Wed, 14 Oct 2020 10:31:45 +0100 Newsgroups dbase.getting-started My recollection is that this occurs when a function returns a value (or no value) which is inconsistent with the expectation that the calling function has, which then uses it in, I seem to recall, the context of array subscripts. But the memory is fuzzy.   Sorry not to be more help.
