Actually, only data is limited to 64K in VENIX. Code can be up to the available memory in size. The loader automatically code maps when the code is greater than 64K.

Nope -- this has not been the case for quite some time! VENIX System V for the PC's allows LARGE code space (limited only by physical memory) and 64kb data space. The 64kb code space was a restriction only in very early versions of VENIX. In fact, using the shared memory capability, you can easily (but not transparently) access large amounts of data space also. ------------- Paul Kleppner VenturCom, Inc. 617/661-1230 {seismo!harvard,genrad!mit-eddie}!cybvax0!vcvax1!paul
