| Cant get Tris command to be accepted on compile, Need help |

Hello,
I'm using the E3 book/board package to learn C, and all has gone well except for this morning when I tried to use the tris command to set the i/o directions separately. Every time I try to compile, it fails and gives me the error: expect declaration.
This is right out of the manual for an example, and won't work
it always highlights the (0x0F) and gives me the error code.
any ideas?
Here is the code:
| Code: | /*I/O testing of ports and pins*/
#include <e3.h>
#use fast_io(C)
set_tris_c( 0x0F );
void main() {
} |

and we're supposed to guess which PIC you're using ???
main has nothing in it, so I'll assume the PIC's going to sleep though without a compiler version, I'm guessing....
also no idea what's in the e3.h file, that could be causing all sorts of 'issues'. |

| The answer is simple. set_tris_x, is a program command, not a preprocessor directive. It has to be in the code..... |

Thank you "Ttelmah". That gives me no errors. Now I can try to send commands to the ports.
Temptronic - Ive gotten in the habit for 15 years of programming micros (obviously with other languages) to compile what I have so far ever so often so I can tell if I made a mistake. This is a base blank program to add to later. The E3 is a small board with an 18F14K50 that CCS sells with a book so you can learn C. Im on the chapter now dealing with ports and I/os.
