 I looked briefly at your test program.  I don't have time to figure out
 exactly what is wrong with it, but I can assure you that Int 21H
 Function 67H does *definitely* work as advertised.  It is only available
 in MS-DOS 3.3 and later though.

 My guess is that even though you think you are restricting the amount of
 memory assigned to the program with the Linker switch, this is not
 really happening, and the program is getting allocated all the available
 memory.  in such a case Int 21H Function 67H will fail because it can't
 allocate a new block to hold the expanded handle table. 

 It could also be that the runtime library's support for this is flakey.

 If you use int86 to resize your program's memory block (say, down to 128
 KB maximum if you are small model) with function 4ah then ask for more
 handles with function 67h it should work as expected.  I just tried it
 interactively from PC/FORTH and it worked fine.
