There
are only three kinds of file in DOS which are directly executable.
These are .exe, .com,and .bat. Out of these, .exe and .com are
executable files. The .bat is batch file or a scripting file.
Whenever
we want to execute multiple commands at a time, we may use the batch
file. We just need to add all commands in a file whose extension is
.bat. This is very usefull while executing a assembly language
program.
For
example, you have written a program named myprog.asm and you
want to assemble, link and execute in one command. Then just create
a file called run .bat and type in it.
masm
myprog.asm;
link
myprog;
myprog
This
file must be present in your current working directory. i.e /masm.
Now, after typing 'run' (name of batch file ) on terminal all above
commands will get executed.
