NAME
     sh - fast execution of an sh shell command

SYNOPSIS
     integer function sh (string)
     character*(*) string

DESCRIPTION
     The function sh gives string to the sh shell as input, as if
     the string had been typed as a command.

     The shell is always the Bourne shell, sh(1).

     The current process waits until the command terminates.  The
     returned value is the exit status of the shell.  See wait(2)
     for an explanation of this value.

     For output files, the buffer is flushed to the actual file.

     For input files, the position of the pointer  is  unpredict-
     able.

     The sh function is not MT-safe.  Do not call it from FORTRAN
     MP programs.

FILES
     libF77.a

SEE ALSO
     execve(2), wait(2), system(3)

BUGS
     string cannot be longer than 1024 characters.
