Problem Statement

This task is about copying a string.

Where it is relevant, distinguish between copying the contents of a string versus making an additional reference to an existing string.

Let's start with the solution:

Source code in the computer/zero programming language

ldsrc:  LDA  src
stdest: STA  dest
        BRZ  done  ; 0-terminated

        LDA  ldsrc
        ADD  one
        STA  ldsrc

        LDA  stdest
        ADD  one
        STA  stdest

        JMP  ldsrc

done:   STP

one:         1

src:         82    ; ASCII
