How to converting numerical value to srting?

[JerryWong]

In the help documentation, there is a case "Converting an Interger to String, sVAR=itos (12)", but when I use the same statement in expression, it says "Couldn't find object for itos.""No fuction itos." I want to converting a numerical value to srting, then make the string as part of a attribute, can't find a way to solve this.

The expression system uses the "stringvalue()" function to convert numbers to strings.

Great. It works well. I wonder is there any book helping to learn Parametric Design or secondary development etc. After doing something as standardiztion, so I can make the design process more efficiency and automatic.
