An archive is a single file holding a collec tion of other files in a structure that makes it possible to retrieve the original individual files (called members of the archive). ... ar is considered a binary utility because archives of this sort are most often used as libraries holding commonly needed subroutines. ... Haven't used it myself, but there should be examples of its use in the makefiles for gcc, etc. (I've seen "ar" commands whiz by, and they seemed to be doing roughly what you intend, as far as a fleeting glimpse can tell.) At least, it's worth a look. Erik
