extracting substring using regex in sas

问题

I have a string like this:

dfjkldjfdsldfkdslfkd dfkdjd/FR018/HAHDFKDLFDAFHDKFJL/ABCD//NAME/I WANT TO EXTRACT THIS/JJJJ//NAME/blah blah blah

in this string, I want to be able to pull the string I WANT TO EXTRACT THIS. In other words, I want to extract everything that follows /ABCD//NAME/ and before /JJJJ.

how can I write this using regular expressions?

thanks

I am not familiar with SAS, but from the documentation it seems like you can do:

re = prxparse('/\/ABCD\/\/NAME\/(.*?)\/(.*?)\/JJJJ/s');
if prxmatch(re, str) then 
    do;
        res = prxposn(re, 1, str);
    end;
