4.7.2 Character String Literals

A character string is a sequence of characters enclosed in double quotes. Double quotes that are part of character strings are represented by two consecutive double quotes. The maximum length of a string varies and is defined for each directive that requires a character string. Characters are represented internally as 8-bit ASCII characters.

These are examples of valid character strings:

"sample program"	defines the 14-character string sample program.
"PLAN ""C"""	defines the 8-character string PLAN "C".

Character strings are used for the following:

Filenames, as in .copy "filename"
Section names, as in .sect "section name"
Data initialization directives, as in .byte "charstring"
Operands of .string directives
