How to reverse a number

[sasuser123123]

Hi

I have a data like
03-455
04-111
09-788
I need output like
455-03
111-04
788-09
is there any direct function for this output instead of separating and combining

Can Anyone explain how to do??

want = catx("-",scan(have,2,"-"),scan(have,1,"-"));

I don't think a solution exists that doesn't separate and combine, at least under the hood. Using prxchange is one way to hide the necessary steps:

want = prxchange('s/(\d+)-(\d+)/$2-$1/', 1, have);
