Additionally, do not use the instruction mnemonics or assembler directives as symbol or
variable names.
Assembler Numeric Representation
Numbers are represented internally as signed 32-bit integers. Floating-point numbers are
32-bit IEEE standard single-precision values. The assembler detects an expression oper-
and that is out of range for the intended field and generates appropriate error messages.
Character Strings
Character strings consist of printable ASCII characters enclosed by double ( " ) or single
( ' ) quotes. A double quote used within a string delimited by double quotes and a single
quote used within a string delimited by single quotes must be preceded by a back slash ( \ ).
A single quoted string consisting of a single character is treated as a character constant.
The assembler does not automatically insert null character (0's) at the end of a text string.
A character string cannot be used as an operand.
For example:
DB "STRING" ; a string

DB 'STRING',0 ; C printable string

DB "STRING\"S" ; embedded quote

DB 'a','b','c' ; character constants
