I like to show how to redirect some assembler mnemonics and debug commands for to telecontrol debug within a batchfile and some pipe(> < ) operators. Description: The first step is to redirect all commands into a temporary textfile and the second step is to redirect the temporary textfile to debug. These following examples have to be copy and paste each one into a new texttfile. And the textfiles have to be renamed with the "bat" file-extension: Example: "Hello.bat" @echo off echo a cs:100>tmp.deb
echo mov dx,108>>tmp.deb
echo mov ah,9>>tmp.deb
echo int 21>>tmp.deb
echo ret>>tmp.deb
echo db “Hello World!$”>>tmp.deb
echo g=cs:100 107>>tmp.deb
echo q>>tmp.deb
debugtmp.inf
del tmp.deb
type tmp.inf

Variation and alternative example with a similar content:

@echo off
echo e cs:100>tmp.deb
echo ba 08 01 b4 09 cd 21 c3>>tmp.deb
echo a cs:108>>tmp.deb
echo db “Hello World!$”>>tmp.deb
echo g=cs:100 107>>tmp.deb
echo q>>tmp.deb
debugtmp.inf
del tmp.deb
type tmp.inf
