I wouldn't even recommend to start understanding the compiler in ncal.pas
as it is one of the more complex parts of the compiler.

The easiest way to debug the compiler is to use the IDE from 1.0.x. That
way you can debug like you could do with bp7.
Then when debugging place a breakpoint at the offencing internalerror()
call and run the program, when it hits the breakpoint you can investigate
the variables and analyze what is wrong. When that is not enough the place
a breakpoint earlier in the program flow and make the breakpoint
conditional with the condition 'aktfilepos.line=<line where compilation
aborts>'. Then you can step through the compiler to see what actually happends.
