Re: writing recursive function ...

Hi,

Thanks Mary. I work around it by putting a while loop but i will try to
convert it to a recursive one. Somehow, the recursive code fails when it
is checking the types. Putting some extra check for variable types is
good idea. Maybe it works. Anyway, thanks for your help.

Regards,
