5.6. The String Operators
Special string operators -- concatenation
(&), equality (eq ),
inequality (ne), and comparison
(lt, gt, le,
ge) -- were required when using string data in
Flash 4. In Flash 5 and later, the special string operators are
deprecated (i.e., supported but obsolete). Use
==, !=,
<, >,
<=, and >= for string
comparisons, unless exporting to Flash 4 .swf
format, in which case you must use the old operators (eq
, ne, lt,
gt, le, ge).
Use + for string concatenation, unless exporting
to Flash 4 format, in which case you should use
add instead of & (because
& is the bitwise AND operator in Flash 5 and
later).
For more details and a list of Flash 4 versus Flash 5
string-operation equivalencies, see Section 4.6, "Working with Strings" and Table 4-2 in
Chapter 4, "Primitive Datatypes".
