+- Motorola's assembler aliases **and #xxx,reg** with **andi #xxx,reg** and can
+  distinguish between the two. rmac needs the user to be explicit and will
+  generate an error if the programmer tries to use syntax from one instruction
+  to the other.
+- Similarly Motorola's assembler can alias **move** with **movec**, **movep** 
+  and **movem**. rmac also not accept such aliasing and generate an error.
+- Motorola's assembler uses the underscore character (*_*) to define local
+  labels. In order for rmac to maintain a uniform syntax across all platforms,
+  such labels will not be treated as local.
+- Macros syntax is different from Motorola's assembler. This includes local
+  labels inside macros. The user is encouraged to study the `Macros`_ section
+  and compare syntactical differences.
+- Motorola's assembler allows reordering of addressing modes **x:**, **x:r**,
+  **r:y**, **x:y**. rmac will only accept syntax as is defined on the reference
+  manual.
+- In **l:** section a dc value cannot be 12 hex digits like Motorola's assmebler.
+  Instead, the value needs to be split into two parts separated by **:**.
