Attached is code that does something similar to what you required. It is a
part of some other code so may not verify as it stands. Please consider it
as an example of what is required.

To convert the value of a numeric variable to a string variable (like the
variable "Str" below), you need to use the "NumToStr" function.

Hope this helps.
