Context-Sensitive Compile Information
After an object has been compiled, the Propeller Tool displays context-sensitive compile

an object. For example, compile this example by pressing F9 (or selecting the Run →
Compile Current → Update Status menu option) and then place the cursor on the

encoded into 32 bits in a way that makes them incompatible with integer values.
