{n}

Interprets n as an integer from 1 to 9. Tagged fields correspond to * or . or [c..] or .* in the search string. The first nine wildcard characters in the search pattern are tagged. If a tagged field that is used in the replace string does not exist, it is replaced by a NULL string.

*nth “*”

Interpreted as {n}, n ranging from 1 to 9. If more than nine wildcard characters exist in the search string and more than nine *'s in the replace string, the system substitutes the first nine *'s in the replace string with the corresponding nine tagged fields from the search string. The remaining *'s in the replace string are substituted with a NULL string.
