You cannot add any instvars to String, since the the run time system & compiler |
130 |
creates literal strings and knows that strings have no named instvars. |

If you really need strings with instVars, you have to create a subclass |
608 | 132 |
of String (the access functions defined here can handle this). |
133 |
A little warning though: not all smalltalk systems allow subclassing String, |
|
134 |
so your program may become unportable if you do so. |
|
1290 | 135 |
|
7895 | 136 |
Strings have an implicit (assumed) encoding of iso8859-1. |
137 |
For strings with other encodings, either keep the encoding separately, |
|
138 |
or use instances of encodedString. |
