Hi everyone. I have the following problems. 1. In pascal program like this ... uses crt; begin ClrScr; .... And it says that there is no reference to crt_clrscr. The same happens when I use C program with #include <conio.h> .... main() ..... clrscr(); .... Where's the problem?

2. When I use a project with a single file *.pas, I have to add these file to the project, do I have to add the units? I metion this because when I add only the *.pas It says that It cannot import the unit. When I close the project and I build all, it works.

Thanks in advance.
