Symbol Names |
Previous | Assembler Symbols | Next |
Symbol names begin with a letter or with .
, _
, or $
.
That character may be followed by any string of digits, letters, dollar signs, and underscores.
Case of letters is significant: foo
is a different symbol name
than Foo
.
Each symbol has exactly one name. Each name in an assembly language program
refers to exactly one symbol. You may use that symbol name any number of times
in a program.
