hi, it is long time ago, but:
1. hook keyboard and timer interrupt
2. place all code that needs to remain resident into beginning of app
3. call DOS interrupt "terminate and stay resident"

uff. i think no one writes these anymore, as DOS is dead. You can find many in MASM and figure out how to rewrite them to FASM, it's easy.

Right.

Check CTMOUSE or other FreeDOS utils. Or SNARF. But most of it will be
MA$M, or NASM at best, no FASM Sad

Er, maybe you'll prefer to get SNARF 1.3 (MASM?) from its homepage (no offense, NTOSKRNL_VXE).

Also, see CTMOUSE.

About MA$M, I prefer to disassemble the binary (if exists, using NDISASM),
and fix up this (looking into the source for label names and comments),
rather than fixing the MA$M source code. The MA$M syntax is
horrible, with all the messing-linking-up of the "sections" and
"segments", and all the useless directives "assume", "tiny", "addr", "offset", ... Sad

IMO this is one of FASM's biggest flaws.

none of these directives is "useless", as you would soon have to realize if you wrote something like FD Emm386 or a similiar project with modules written in different languages and using a segmented memory model.

Anyways, Vasilev, look at Simtel.net (under Home › Utilities/Drivers/System Files › Terminate and stay resident utilities) or Garbo's FTP for some utils.

You can do better with MASM, I with FASM Wink

Well, if I had to fix up JEMM386, CWSDPMI or HDPMI32 or a similar project,
I would completely disassemble it with NDISASM and port to FASM -
no "C" at all Shocked

Perhaps he should say instead, "Use the DOS version or run this under HXRT w/ MSVCRT.DLL." Smile

Make sure you actually try it first (running FASM/Win32 console under HXRT: I still haven't, sorry, didn't mean to be misleading ... I was too stubborn/lazy to try digging up MSVCRT.DLL from my old Win95 install disks, but I'm fairly certain that it should work).

EDIT:
Hey, Vasilev, also check out Toddy (free DOS cmdline editor TSR, like DOSKEY, w/ Wolfware ASM src).

Also check out the FreeDOS resident calculator.

EDIT: Screen saver for DOS? See MYSTIC.ZIP and Sleeper from WASM223.ZIP.

There seems to be little interest to write tsr programs.
I was looking some of my own (and very old) tools.
They are written for ArrowsoftAsm/TASM syntax, They have been used under 486 with dos v6.22
Probably WinXP don't like some of my tricks.
You are free to copy paste if you find something useful.
Code:
Program list of tsr_pak.zip

clock    - tiny tsr clock
filelog  - log dos file calls
grabvesa - save capture to pcx with vga,vesa v1.2 (HotKey: <Right Shift> double click)
hexview  - memory hexdump utility (HotKey: Alt-F12)
tsr_tet  - tiny tsr tetris (HotKey: Ctrl+T)
tsrdebug - tsr version of tiny debug (HotKey: Alt+F9)
zoomvesa - zoom vesa v1.2 screen (HotKey: Ctrl+F11 and Ctrl+F12)
