Sorting
 
  These programs perform sorting on various types of input data. Some
routines work from a presort table [sisort] while others assume some
special record/trace arrangement is true [resorter]. Some routines require
that the input be a diskfile [sisout] while others you can pipe data into
but require a diskfile on output.
 
WARNING: Failure to meet the requirements for a given routine may result
in very strange occurances [such as massive file generation and disk overflow].
