sas, prchange, reg ex, unstructured data

user112a2 — Fri, 26 Apr 2019 15:53:04 GMT

I am looking through someone's code. What does this piece of code do? I am getting better at PRXCHANGES and regex's. I am not a pro yet but still learning. It looks to me like it is replacing something like P.O. BOX with PO BOX. Does \s? mean optional spaces? and 0? mean 0 is optional? Also :? means : is optional? Looks like I may be understanding some of it. Thanks

The question mark stands for zero or one occurrence. So you could use the folowing to look at all the replacements

X='ABC0 P.O. BOX: 123';
