 # Compiler Warning (level 1, Error) C4235
 
 > nonstandard extension used: '*keyword*' keyword not supported on this architecture
 
-The compiler doesn't support the keyword you used on the architecture your build is targeting.
+## Remarks
+
+The compiler doesn't support the keyword you used on the architecture your build is targeting. For example, the [`__asm`](../../assembler/inline/asm.md) keyword is not supported in x64 builds.
 
 This warning is always issued as an error. Use the [warning](../../preprocessor/warning.md) pragma to disable.
+
+## Example
+
+The following example generates C4235 as the [Inline Assembler](../../assembler/inline/inline-assembler.md) is only supported on x86:
+
+```cpp
+// C4235.cpp
+// processor: x64
+
+int main()
+{
+    __asm nop   // C4235
+}
+```
