Hi Statalist,

I am trying to extract part of string variable that looks something like this:


The occurrence of 1, 2 and 3 are randomly placed and no predefined order. I am trying to obtain just the numeric part of the variable so that I am able to retain the order of numbers: 123, 132 and 211 in the example above. Hence, I am only trying to remove the dots (.) from the string variable.

I am running Stata 13 on Mac 10.9.

Thanks for your help.
