2 routines for R14 to save drawings in R12 and R13 format, respectively.
Dumais & Associates, Inc., Jeff Foster/The CAD Shack, January 7, 1998
These routines perform a one-step "saveas" in R12 or R13 format adding _R12 or _R13 to
the current drawing name (so you can keep all those duplicate files straight). Useful for
reformating files to be sent to clients who are still using earlier releases of AutoCad.
