(MS may call this facility Dynamic Link Libraries; one OS reference (Dietel) calls it Dynamic Loading.) If it doesn't, how does one escape re-compiling everything when a core library such as libc or libresolv is replaced, when one moves for example. from Bind-4 to Bind-8 ? I'm sorry to be so ignorant about this but I haven't seen any mention of these matters in the Sys Admin references suggested by the handbooks bibliography (Fraesch, Nemeth et al). How do commercial Unixes (such as AIX 3.2.5) deal with this ? While I'm always comfortable re-installing FreeBSD, AIX is another matter. Thank you very much, Yours sincerely S Hopcroft
