*ERROR 55 -- the ordinal values of components of sets are restricted
to being in the range 0..255
Appendix A
The Pascal standard does not prescribe any limits on the range of ordinal
values that components of sets may take. This implementation restricts the
ordinal values of all components of sets to the range 0..255.

*ERROR 56 -- the name of a type is required here
This error indicates that the compiler expected an identifier which has been,
or is to be declared as a type. The common cause of such errors is
attempting to define types explicitly (e.g. 1..10) rather than giving them a
name in a TYPE declaration first.
