Regex search in enhanced editor

Every one has its own habit.

I always edit text in Ultraedit. I like the Regex search/replace functionality in Ultraedit so much as I maintain a list of common Ultraedit-style Regex string.

I know that SAS enhanced editor must have this functionality. However, I got no information for Regex grammar from SAS online doc.

Today, I find the Regex magic box incidentally. :)
