Your misconception lies in thinking that "strings" are a concept in
their own right, as opposed to simply a number of "values" stored after
each other.  This is almost certainly a bad habit you learned from
BASIC.

The EQUS operator is nothing more than a convenient shorthand, like ADR.

EQUS "Some text"+CHR$(0):ALIGN

Is equivalent to:

EQUB 83
EQUB 111
EQUB 109
EQUB 101
EQUB 32
EQUB 116
EQUB 101
EQUB 120
EQUB 116
EQUB 0
EQUB 0
EQUB 0

One of the common threads in your posts, such as this one, is that you
have serious conceptual problems with the idea of pointers[1], which is
something you simply cannot have your knickers in a twist about if you
are to have any hope of succeeding in assembler.  See also: ADR versus
LDR.

Your problems are not with assembler, but are more deeply rooted in some
of the fundamental concepts of programming as a whole.  Assembler simply
happens to be the language you are currently attempting to learn.
