I cannot confirm this behavior. If n!! is too large, I get MAXR, i.e. 9.99999999999E499.
You must be using ZINTs, then. As a matter of fact, I wrote the code with an HP-48 in mind, so it is primarily intended for floats.

Again, this must be a ZINT-specific message.

P.S. Thanks for reminding me of the missing "END", I just added it.
