This article deals with having a TPU editor as a child process and being
able to switch it between the foreground and the background. This is not
the only or best way of dealing with this problem.
------
add the following command to login.com
$tpu :== @sys$login:tpu
------
extact this article and put the following lines in the file tpu.com
$! copyright 1987 by Chris Seline
$! tpu.com so that invoking tpu the first time creates a subprocess
$! and after that one attaches back to it using fg, and CTRL-Z in TPU will
$! write your current buffer and move TPU into the background.
$!
$ if p1 .eqs. "" then inquire p1 "File"
$ assign/user tt: sys$input
$ spawn/proc="{{{{{{TPU}}}}}}" $edit/tpu/com=sys$login:tpu-fg-bg.tpu 'p1'
$ fg :== attach "{{{{{{TPU}}}}}}"
-------
put the following lines in the file tpu-fg-bg.tpu
! tpu-fg-bg.TPU designed so one can write and attach to parent process
! Chris Seline
PROCEDURE cjs_ctrl_z;
WRITE_FILE (current_buffer);
ATTACH;
ENDPROCEDURE;
!
DEFINE_KEY ('cjs_ctrl_z', CTRL_Z_KEY);
MESSAGE ("<CTRL-Z> to write and attach");
--------
TPU will spawn a TPU editor
CTRL-Z will bring you back to your parent process
fg will bring you back to TPU
