As a very satisfied Moi user, and an amateur script writer, today I noticed a scripting error which I made.
In the context of number entry, "unsignedintegerinput" permits the entry of positive integers.
"integerinput" permits the entry of positive and negative integers.

For "unsigned integerinput", the space is incorrect. The space must be removed, to avoid the entry of negative integers.
The error has propagated to nearly all of the scripts which I have written. :-(
