Thank you very much, Leonid, for one more treasure! The language is clear and text is very constructive and logical! I am always jealous when I see your articles - I wish I have a chance and time to learn all these tools! It is like getting into a LEGO store for a child with very limited money. People who overwhelmed with daily projects and endless routine in their jobs sometimes are just dreaming about the way to get into the space - open SAS space, that now has the name SASjs! You defined goals and described their structure, which means a start. I found very interesting macros in the MacroCore Library and definitely going to use some of them! JavaScript is on my plate too. Delicious!
