Donald,

Sad to hear that it is documented like it is, given that some FPA article *did* mention the behaviour you got.

I must admit that when I read that in FPA I thought that having *any* command/function error-out was not at all the best design. So hopefully what had been documented will some day come to pass

Cheers,

Jim N
