	The MOST v3.03FM which is bundled with CSWING (patches recently posted
to vmsnet.sources) has a callable interface (most_less() in main.c), but the
build procedure also creates a "standalone" MOST.EXE for use from the DCL
prompt.  The latter's exit routine positions the cursor at the screen length
less one line, so that the carriage return added by the system will position
the DCL prompt at the bottom of the screen without causing the MOST display to
scroll.

	If a program invokes the standalone via spawns with lib$spawn() or
system(), rather than using the callable interface, you get the intended
behavior after the first spawn but after subsequent spawns the carriage return
isn't added and the cursor stays positioned at the screen length less one
line.  I have no idea why lib$spawn() and system() behave that way ;-(.  This
is not a problem if your program immediately re-invokes an smg$ or curses
screen, but if the spawns are followed by a screen output function such as
printf(), which starts outputting from wherever the cursor is, after the
second and subsequent spawns the output appears on what was MOST's
reverse-video "filename and status" line rather than beneath it (ugh, that's
ugly 8-).  Your program must explicitly position the cursor at the first
column of the bottom line to get consistent behavior after every spawn (I
suspect this is the case for any VMS emulation of MORE invoked via spawns).

	If you're using MOST as the pager in VMS versions of the GOPHER
client, here's a quicky hack you can make in display_file() of ourutils.c to
deal with the problem for VT terminals or emulators:


GOPHER client v0.6d:

     if (strcmp(PagerCommand, "builtin") != 0) {
	  system(command);
#ifdef VMS
          printf("\033[%d;%dH", LINES, 1);
#endif
     }
     else
	  Ourpager(Filename);


GOPHER client v1.1beta:

     if (strcmp(STRget(PagerCommand), "builtin") != 0) {
	  system(command);
#ifdef VMS
          printf("\033[%d;%dH", LINES, 1);
#endif
     }
     else
	  Ourpager(Filename);
