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
     arguments in system calls and execute them out of line in
     the data segment.  This preserves the purity of the text
     segment.

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