PL/SQL Package compile Problem

First I am fairly new to PL/SQL programming(about six months). To compile a program. I get into sqlplus and type @xxx.pkg. If I get errors I type show errors and then list 20 30 to see where the error on line 25 is. All of a sudden while compiling a package containing three functions, I go to compile and get alot of errors on various lines. When I go to list them list 30. It says no such line. When I type list by itself which usually lists the whole progam. I get the last three lines.

	Begin
	   NULL;
      End WriteDocPkg;

What happened? I cant fix the errors because I can't list the program. This happened all at one time. Is there some switch I inadvertently turned on?

Please Help
