If you are experiencing trouble with jimsrand(), i.e., if you receive
the following message:
Enter TRACE:2
It is likely that random number generation on your machine
is different from what this emulator expects.  Please
take a look at the routine jimsrand() in the emulator code. Sorry.
try changing line 186 in distvec.c from
  double mmm = 2147483647;   /* largest int  - MACHINE DEPENDENT!!!!!!!!   */
to
  double mmm = 32767;   /* largest int  - MACHINE DEPENDENT!!!!!!!!   */
If that still doesn't work, download testrand.c, compile and run it.  It will produce a
number and you should use that number.
