IIRC, these "SAS/C" modules was delivered as a part of these SW's own libraries, not as a part of the SAS product. (I call these "SAS/C" as that was what I saw when browsing the loadmodules.) In fact, one of the SW's was ISPF/WSA and the other (IIRC) was a product called ProEdit. BTW, what do You mean by "prefixed the library" ?
