(Motif 1.1, DEC PMAX (Mips-chip), MIT X11R4 Server)

I have a multi-line text widget, called text, that contains a lot
of text.  I would like to remove this text, so I try this:

    erik[0]='\0';
    XmTextSetInsertionPosition(text,0);
    XmTextSetString(text, erik);

And the text is still there.  It has the XmNeditable resc. set to True.

Since that didn't work, I tried:

   XtDestroyWidget(text);
   ac = 0;
   XtSetArg (al[ac], XmNrows, 24);  ac++;
   XtSetArg (al[ac], XmNcolumns, 80);  ac++;
   XtSetArg (al[ac], XmNresizeWidth, False);  ac++;
   XtSetArg (al[ac], XmNresizeHeight, False);  ac++;
   XtSetArg (al[ac], XmNscrollVertical, True);  ac++;
   XtSetArg (al[ac], XmNeditMode, XmMULTI_LINE_EDIT);  ac++;
   text = XmCreateScrolledText (parent, "text", al, ac);
   XtManageChild(text);

which did work but is a bit brutal for my tastes (besides, I would have
to rewrite a LOT of code to make that work right).

What is the 'best' way to remove text from a Text widget?
