Thanks a bunch. This is perfect. :-) I was hoping that this would be done soon, but for the life of me I can't seem to find anything but the full release tar balls online. Is there a CVS somewhere?

What about the possibility of running arbitrary commands? Specifically, I would like to run a few setenv commands upon reattach (based on the attach-from environment).

About this patch, shouldn't the last line be "FindNiceWindow(fore, NULL)" or "FindNiceWindow(fore, '\0')"? I've noticed that the screen code really likes to use just plain 0 where it means NULL, or '\0', or "". Would patches to fix this be accepted?

Thanks again,

Creating new windows when attaching is not hard, the next screen
version will support it if you use '-p +'. Here's the part of
the code:

socket.c, in FinishAttach:

  if (*m->m.attach.preselect)
      if (!strcmp(m->m.attach.preselect, "="))
        fore = 0;
      else if (!strcmp(m->m.attach.preselect, "-"))
          fore = 0;
          noshowwin = 1;
      else if (!strcmp(m->m.attach.preselect, "+"))
          struct action newscreen;
          char *na = 0;
          newscreen.args = &na;
          DoAction(&newscreen, -1);
        fore = FindNiceWindow(fore, m->m.attach.preselect);
    fore = FindNiceWindow(fore, 0);
