Question

What is the difference between using a single quote ‘ or a double quote ” in nasm? Does it have any affect on defining variables, or nesting quotes?

Answer 1

From NASM’s manual:

A character string consists of up to
eight characters enclosed in either
single quotes (‘…’), double quotes
(“…”) or backquotes (...). Single
or double quotes are equivalent to
NASM (except of course that
surrounding the constant with single
quotes allows double quotes to appear
within it and vice versa); the
contents of those are represented
verbatim. Strings enclosed in
backquotes support C-style -escapes
for special characters.
