--------D-2180-------------------------------
INT 21 - European MS-DOS 4.0 - "AEXEC" - EXECUTE PROGRAM IN BACKGROUND
AH = 80h
CX = mode
0000h place child in zombie mode on exit to preserve exit code
0001h discard child process and exit code on termination
DS:DX -> ASCIZ full program name
ES:BX -> parameter block (as for AX=4B00h)
Return: CF clear if successful
AX = Command Subgroup ID (CSID)
CF set on error
AX = error code (see AH=59h)
Program: European MS-DOS 4.0 was written for Siemens in Germany and then used
by several other European OEMs; its release falls between mainstream
versions 3.2 and 3.3
Desc: asynchronously execute a program, creating a new process for it
Notes: this function is called by the DETACH command
there is a system-wide limit of 32 processes
the CSID is used to identify all processes that have been spawned by
a given process, whether directly or indirectly
programs to be run in the background must use the new executable format
(see AH=4Bh)
background processes may only perform asynchronous (background) EXECs,
either this function or AX=4B04h
background processes may execute INT 11, INT 12, INT 21, INT 2A, and
INT 2F at any time; they may execute INT 10 and INT 16 only while
they have opened a popup screen via INT 2F/AX=1401h; no other
interrupts may be executed from the background
background processes may not use drive B: or overlay their code
segments
see AX=8700h for an installation check
the "NE" new executable format made its first appearance in European
MS-DOS 4.0
SeeAlso: AH=4Bh,AH=87h,INT 2F/AX=1400h"POPUP"
----------218080-----------------------------

BX = flag (00h freeze command subtree, 01h only specified process)
CX = Process ID of head of command subtree
Return: CF clear if successful
CF set on error
AX = error code (no such process)
Desc: temporarily suspend a process or a process and all of its children
Note: if BX=0001h, this call will not return until the process is actually
frozen, which may not be until after it unblocks from an I/O
operation
SeeAlso: AH=82h,AH=89h,AX=8E00h,INT 15/AX=101Dh
--------D-2182-------------------------------
INT 21 - European MS-DOS 4.0 - "RESUME" - RESTART A PROCESS

process
Note: if the partition size is set to 0000h, no partition management is done
and all memory allocation is compatible with DOS 3.2.
the partition size can be changed regardless of what use is being made
of the changed memory; subsequent allocations will follow the
partition rules (foreground processes may allocate only foreground
memory; background processes allocate background memory first, then
foreground memory)

restriction on the name)
on successful creation, the reference count is set to 1
SeeAlso: AX=8401h,AX=8402h,INT 15/AX=DE19h

AH = 86h
BX = total number of file handles in new table
Return: CF clear if successful
CF set on error
AX = error code (06h,08h) (see AH=59h)
Desc: adjust the size of the per-process open file table, thus raising or
lowering the limit on the number of files the caller can open
simultaneously
Notes: any currently-open files are copied to the new table
if the table is increased beyond the default 20 handles, only the
first 20 will be inherited by child processes
error 06h is returned if the requested number of handles exceeds
system limits or would require closing currently-open files
SeeAlso: AH=26h,AH=67h

Notes: called by MS C v5.1 getpid() function
this function apparently must return AX=0001h for INT 21/AH=80h to
succeed
one possible check for European MS-DOS 4.0 is to issue this call with
AL=00h and check whether AL is nonzero on return
