SYSTEM(3F)          RISC/os Reference Manual           SYSTEM(3F)



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 com-
     mand interpreter (shell); otherwise 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 explanation of this value.

FILES
     /usr/lib/libU77.a

SEE ALSO
     exec(2), wait(2), system(3).

BUGS
     string can not be longer than NCARGS-50 characters, as
     defined in <sys/param.h>.
