tasm_tbt

Brief

DOS emulation environment configuration in addition to the assembly of the work unit to run some of the code snippets .asm implemented and/or prototypes made some time ago as an initiation to this language. -> "If you have any doubts, open an issue"

Set up environment

• Download and install the emulator
• Set up the working folder

cd ~/Desktop
git clone https://github.com/cristianrubioa/tasm_tbt.git
cd tasm_tbt/

• Print working directory pwd

pwd
> /Users/<user>/Desktop/tasm_tbt      #e.g. path

Mount unit

• Open DOSBox
• Configure keyboard input

keyb sp 850

• Mount working directory

MOUNT C: /Users/<user>/Desktop/tasm_tbt

Test unit

1. Test debug.exe

• Multiplying two numbers in assembly MS-DOS see in gist

# To view memory, enter programs into it, 
# and track its execution
debug
a100

# Clean records and multiply
sub ax,ax
mov cx,4
add ax,8
loop 105
nop

# View and execute the process 
# for each instruction
r
t

2. Test TASM.exe and TLINK.exe

• Take a .asm code and generate executable, bandera.asm for example

tasm mayus.asm
tlink mayus.obj

# Run
mayus

Note: is the same step for each .asm file.

Snippets:

• rescal.asm -> Resistor color calculator prototype (unfinished)
• mayus.asm -> Convert text to upper case
• minus.asm -> Convert text to lower case

EMU8086:

8086 microprocessor emulator with built-in assembler.

• Install emu8086 emulator found in the folder

Note: with this emulator you can also program in assembly language since it has an integrated editor.
