in which instance,as follow should be added a ing?
look at the web:
the guy says:
Buy joint cross type spicer,codes as following
why use "as following",but not "as follow"?

答案

I am not sure.But maybe it will help you.
As to as follow/as follows,we usually use it as adv.,namely,we tend to use as follows when it follows verb.eg.do it as follws
As to as following,personally I think it could be divided into as & following,following here used as adj.(sometimes maybe noun.）eg.as following codes,tips as following.
Anyway,as following has something to deal with noun,while as follow(s) has something to deal with verb.
codes as following,as following codes,noun is placed ahead so as following is used
