Noctal is a helper library, developed by me, for beginners trying to program in assembly using the NASM assembler and Linux syscalls (64bit)
This is specially useful to those who have been programming in some high level language before and want to get to know the computers at a deeper level. This gives them a friendly handshake with the language one step higher than the binary itself.
To use Noctal in your code, you will have to download the std_notcal.asm and std_noctalm.asm files into your wokring directory as well. Then include std_noctal.asm in your main.asm. Then, considering, your asm file name is main, you can use the following commands from your working directory:
nasm -felf64 main.asm -o main && ld main -o a.out && ./a.out
Currently, it has the following procedures/functions/subroutines/labels/everything_else.
