                      5: 
                      6: Below is the procedure I followed to allow enough memory for GnuEmacs to run
                      7: on my 3b2/400. The end result of this is that a process can snarf up to 2Mb
                      8: of memory. This can be a bit dangerous on a 2Mb machine, but I tried it and 
                      9: it worked ok.

                     30: instead of MAXMEM.
