what's wrong with set bind [ user pass ] in config 'self pick db-port 1

if there were a lot of fields (rather than the two in this example) the existing syntax is shorter. The only time there is a significant advantage to the REP is if you want to set words in several objects at once. For those situations I recommend using something like the function below in place of 'bind... bind-with: func [ words obj-set /copy ] [ if copy [ words: system/words/copy/deep words ] foreach obj obj-set [ bind words in obj 'self ] return words ] I wrote this around a year ago when I needed something like a context hierarchy in one of my scripts. - Cal Dixon
