Int 78  - Uofsalford Dbos Dos Extender - Api                               [E]

   AH = function
       00h (PB) display 32-bit memory specified by command argument
       01h (PT) display 32-bit instruction(s) specified by command arg
       02h specify offset to subsequent PB and PT commands
       03h switch to protected mode
       DWORD following INT instruction point to map; protected-mode
             entry point is immediately following the DWORD

       Return: never

       Note:   if bit 31 of the map address is set, only a stub was
             loaded by DOS and DBOS will load the entire program
       04h specify that subsequent load (AH=03h) should leave program in
         memory
       05h release program from memory
       06h set break point at address and option count from commandline
       07h resume program execution
       08h single-step program
       09h set read/write breakpoint using 386 debug registers
       0Ah set write breakpoint using 386 debug register
       0Bh set memory byte to new value
       0Ch display CPU registers
       0Dh run until specified program address reached
       0Fh print trace from program map
       10h specify an offset using a map symbol
       14h print memory without any offset
       18h switch DBOS into/out of test mode (ON/OFF commandline args)
       1Dh get address of real/protected-mode communication buffer

       Return: ES:BP -> comm buffer
       1Eh set real-mode memory size (specify how much real-mode memory
         to leave free when running FTN77 programs)
       22h uninstall DBOS
       24h force DBOS to emulate coprocessor instructions
       26h set named DBOS switches from commandline
       27h reset named DBOS switched from commandline
       2Ah set list of dynamic link libraries to contents of commandline
         file
       35h specify that subsequent load (AH=03h) should stop at first
         instruction

Return: ???

Notes: DBOS supports functions 00h through 50h; many of these functions
     provide a low-level debugging interface
   command arguments are read from the calling program's PSP
