261.0. "need spawning commands internal to a task" by CYRUS::POKALLUS () Tue Feb 21 1989 10:50

I am new to the decwindow environment.  I have been request to convert
several applications that spawn another task from within its code
such as an editor, a special program, etc. that require their own windows.

Under the VWS environment the following summary of commands were used in
the applications code:

     UIS$CREATE_TERMINAL -  get new terminal name

     SYS$ASSIGN -  assign channel to new terminal


     LIB$SPAWN  - spawn task giving it the new terminal name for input and 
                  output.

What is equivalent under the Decwindow environment?

Can anyone help me and/or give me some example(s)?

The notes that I have seen in this notes concerning spawn doesn't seen to
be much of any help to me.  The terminology seen to be quite different -
widget, gadget, etc.

thanks,

ken p.

Look up DECW$TERM_PORT in the DECWindows RELEASE NOTES, then be warned that
					 -------------
there are several bugs in DECW$TERM_PORT that have been identified, and
will be fixed in V5.2.

	- It cancels all your timers
	- It does something funny with the stack that requires you to
	- clear the stack above it to get to work reliably.

See the DECTERM conference (HANNAH::DECW$DISK:[PUBLIC]DECTERM) for more
information.

  The following reply contains a description/design of something we call the
"Task Widget" for use by DTM (it's not really a widget but that's how we 
refet to it).  It describes how DTM creates and controls DECterms and 
subprocesses for executing DCL commands.

  If you would like the sources, I can send them to you.

  On second thought, I'll just mail you the design.
