       1mrandom 4m22mlimit24m | 1mseed 22m?4mseedval24m?
              Generate  a pseudorandom integer number greater than or equal to
              zero and less than 4mlimit24m.  If 1mseed 22mis specified, then  the  com-
              mand  resets  the  random  number  generator to a starting point
              derived from the 1mseedval22m. This allows one to  reproduce  pseudo-
              random  number  sequences  for  testing purposes.  If 4mseedval24m is
              omitted, then the seed is set to a value based on current system
              state  and  the current time, providing a reasonably interesting
              and ever-changing seed.
