Hi all;

i am new in programming area.First of all i have a question about MCS include files.
i wrote the codes in MCS but it didn't compile because of the include files.When i used the pics for example 18f452 or 16f84a it works well because crystal or mclr or timer is external.(Of course it's my opinion it may be wrong).

The other pics are like 16f628A or 16F877A or 16F819 didn't work beacuse of it hasn't got external timer or crystal.

i attach my program codes and pics below.



i wrote an example program

then i press compile button

it wrotes this error codes



please help i must wrote a program with hurry.

thanks everybody
