    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.
