All of the operators are now passed over to the new data tables and primitive search. I'm moving onto intrinsics. These are small routines with function-like that often generate inline code, such as peek, inp and sizeof.

Many of these have quirks such as accepting multiple types, or a typedef. The quirk of Abs is unsigned values: in doesn't affect them. I could raise an error but it's nicer to fake the data to not generate any code.

An extract from the primitives spreadsheet. The row for Integer type is normal. The next two rows are for Byte and Word input types. The 'Proc' column contains 'empty' which signals the code generator to not generate any code.

I'm moving intrinsic to use the same data structure as a user created function. The compiler can then reuse the same code for parameter parsing and validation. I do this using an special calling convention 'Intrinsic' which is not available in users code.

And the type system now contains 'SuperTypes' to handle concepts such as 'AnyInteger or 'any Enumerated type'.

The image shows an extract from the data table for intrinsics which maps onto function definitions.
