===8<==============Original message text=============== Simon, Thanks - that certainly does the trick.

Simon,
Thanks - that certainly does the trick. Though why there should be a warning message there at all is still beyond me (see the title to this thread!).
I can't find any reference in the manuals to the syntax of calling functions like this. There's a list of functions in the Notation and Internal reference manuals, but I can't see where it tells me how to use them, apart from the odd example of specific functions.
Best regards,
Peter
