public interface ConstantsInterface

The ConstantsInterface contains the constants used in all parts of the compiler to ensure a better readability and understanding of the source code.

To avoid an accidential misuse all constants have different values (except some values of error numbers which are equal to keywords). The ranges for these values are:

100- 199 Keywords

200- 299 Special Characters

300- 399 Numbers

400- 499 Identifiers

500- 599 Grammar Constants

1000-1099 Lexical Errors

1100-1199 Syntactical Errors
