 NAME
      fork - create a copy of this process

 SYNOPSIS
      INTEGER*4 function fork()

 DESCRIPTION
      Fork creates a copy of the calling process.  The only distinction
      between the 2 processes is that the value returned to one of them
      (referred to as the `parent' process) will be the process id of the
      copy.  The copy is usually referred to as the `child' process.  The
      value returned to the `child' process will be zero.

      All logical units open for writing are flushed before the fork to
      avoid duplication of the contents of I/O buffers in the external
      file(s).

      If the returned value is negative, it indicates an error and will be
      the negation of the system error code.  See perror(3F).

      A corresponding exec routine has not been provided because there is no
      satisfactory way to retain open logical units across the exec.
      However, the usual function of fork/exec can be performed using
      system(3F).
