\literal.str\

Generally, it does not matter which types of quotation marks are used on literals (strings). Some statements, such as heading and footing impose certain restrictions on their use.

num.exp \ num.exp

The \ can be used anywhere single or double quotation marks are used.

if answer = \quit\ then stop

Typically, the \ is used when executing a TCL string expression in FlashBASIC or BASIC. The AQL heading command requires the use of both single quotation marks, as options, and double quotation marks.
