C is supported so you can invoke the others via C (or via a pipe or
socket to a process running another program).

The external interface in Pop-11 has many levels of complexity.
The simplest level is described in HELP EXTERNAL and
HELP NEWC_DEC

More complex matters are in REF EXTERNAL, REF DEFSTRUCT
REF EXTERNAL_DATA, and lots of X-related documentation files in
	$usepop/pop/x/pop/ref/*
	$usepop/pop/x/pop/help/X*

See also
	HELP RUN_UNIX_PROGRAM
which provides facilities for running other programs and communicating
with them via pipes.

You may get more specific help if you post a precise description of what
you want to do.

(I am not an expert on the external interface as I do everything in
Pop-11!)
