Appending or inserting characters (dashes for SSN)
I'm trying to take an unformatted social security number and insert the dashes into it. I'm getting a value in PID-19 like this: "123456789" and would like to use a data transformation to set the value in PID-19 to "123-45-6789".
I can't find any insert or append functions and I can't find anything in the Intersystems doc repository that would do this. Can someone help point the way for me please? I would like to keep this as a "set" action in my DT. I'm a little new to calling classes so it would be helpful if you included some syntax that would go in the "Value" field. I've been pecking at this for several hours and would appreciate any assistance.
