PL/SQL does not recognize CASE WHEN ELSE END construct as a valid expression

Hello,
did anybody come across the following on Win2K Ora 8.1.7.0.0 EE?

While I am allowed to use the CASE WHEN ELSE END construct within ordinary SQL, I cannot use it within PL/SQL modules (syntax error occurs). On the other hand I can use the DECODE function, although it's harder to code in certain cases.
I couldn't find any document stating that PL/SQL does not support this feature.

Bye...
