INDIR(II)                     8/5/73                    INDIR(II)



NAME
     indir - indirect system call

SYNOPSIS
     (indir = 0.; not in assembler)
     sys indir; syscall

DESCRIPTION
     The system call at the location syscall is executed.  Execu-
     tion resumes after the indir call.

     The main purpose of indir is to allow a program to store ar-
     guments  in system calls and execute them out of line in the
     data segment.  This preserves the purity of  the  text  seg-
     ment.

     If  indir is executed indirectly, it is a no-op.  If the in-
     struction at the indirect location is not a system call, the
     executing process will get a fault.
