Known issues

The following issues affect the content of the Developer Library 6.1 edition at publication date, Q2 2002:

Example code referred to in the documentation may not be present on all SDKs. This includes the Hello World example described in Developer's Guide, Hands On, and the examples used in the Context Sensitive Help Guide and the Installation Guide, both located in the Tools and Utilities section. See Symbian's Developer Network website for example code downloads.

In some parts of the Developer Library, Symbian OS is referred to as EPOC. Also, Symbian OS versions may be referred to using terminology that is now deprecated. For instance, EPOC Release 5 or ER5 refers to Symbian OS v5. ER5U or ER5.1 both refer to Symbian OS v5.1.

The following tools, documented in the Tools And Utilities section may not be present on all SDKs: the command line CSHelp compiler, the CSHelp Compiler GUI, the Application Development Wizard (MEAD) and the Menu Builder.

The documentation of the font compiler, fnttran.exe is incorrect for Symbian OS v5.1 and onwards.

There are occurrences of the macro _L in code fragments in the documentation. This usage is now deprecated in all but a few exceptional cases, and should be replaced by the use of _LIT and explicit constants.
