Thanks Maarten!

I already checked "-help random_number_functions-", but I still can
not find the answer to my question.

I knew that I can use a formula similar like this:
Var=a+int((b-a+1)*runiform()), to keep a specific range in [a,b]
and use another formula: Var=invnorm(uniform())*SD+mean, to keep
specific Standard deviation and mean.
But I do not know how to generate a "Var" with all specific range, SD, and mean.
Please note that I do not generate a sample data from the actual data,
what I want to generate is synthetic data (totally fake data).

Your answer to my second question is exactly what I want.

I appreciate your help!!
