maybe used, but the opening and closing quotes must be the same.
4.3.5 Identifiers
Assembly identifiers are user-defined symbols representing memory locations or numbers. A sym-
bol may contain any number of characters drawn from the alphabetics, numerics and the special
characters dollar, $, question mark, ? and underscore, _.
e.g. Fred is not the same symbol as fred. Some examples of identifiers are shown here:

This comment string may also be used in assembler source to achieve the same effect for loca-
The default radix for all numbers is 10. Other radices may be specified by a trailing base specifier
Hexadecimal numbers must have a leading digit (e.g. 0ffffh) to differentiate them from identi-
Note that a binary constant must have an upper case B following it, as a lower case b is used for
In expressions, real numbers are accepted in the usual format, and are interpreted as IEEE 32-bit
Multi-character constants, or strings, are a sequence of characters, not including carriage return
The first character of an identifier may not be numeric. The case of alphabetics is significant,
