How do you actually physically get to a place in the computer that lets you code in binary...
To code in C++, you go to a text editor or a compiler.
To code in Pascal, you do the same.
To code in BASIC, you do the same.
To code in Assembly, you enter Debug in DOS, an assembler, a text editor, etc...
But what about binary?
A hex editor is hex...not binary...
An assembler is assembly...not binary...
Where can you actually physically code in binary in a computer...
