NAME
system - execute a UNIX command
SYNOPSIS
integer function system (string)
character*(*) string
DESCRIPTION
System causes string to be given to your shell as input as if the
string had been typed as a command. If environment variable SHELL is
found, its value will be used as the command interpreter (shell); oth-
erwise sh(1) is used.
The current process waits until the command terminates. The returned
value will be the exit status of the shell. See wait(2) for an expla-
nation of this value.
