I think substr could be use both numeric and charteric variables. But I have used 'PUT' to change first.
The "str" portion of "substr" implies that you are working with a string, or character variables.
Yes you can convert your numeric variable to a character variable by using the Put function or by creating a new character variable equal to your numeric variable, but in the end the substr function is still evaluating a character string.
It is probably in your best interest to use one of the alternative methods provided here on the thread however.
They are a lot simpler.
Thanks for taking time to explaining to me.
