hello friend
I have a problem with compiling my project.
The compiler opened a new tab with the name of my device pic16f877a and made error that "can not change device type this far into the code" and five other error that all are about that tab--> pic16f877a
I couldn't understand what should i do. Please help me

This is my code:

The device definition must always come first.
| Quote: | #include <main.h>
#include<16F877A.h>
#include<stdlib.h> |
Move the second line to the first position.

Hi,
You aren't using the hardware UART with either the GPS or the SMS modem. Is that your intention?
As coded, I don't think there is much chance of your project working as you hope. You really need to implement an interrupt driven serial routine for the GPS data.
Which GPS and SMS modem are you using?

couple other points...
1)...
#use rs232 (baud=9600,xmit=PIN_B0,rcv=PIN_B1,stream=GSM)
#use rs232(baud=4800,xmit=PIN_B1,rcv=PIN_A0,stream=GPS)
...
you've got Pin B1 used for BOTH rcv and xmt depending on the stream. I don't think you really meant that to happen..
2) ...
if(hbeat>90)
{
fprintf(GSM,"***ALERT***low heart \r\n");
}
... probably mean HIGH heart, not low heart as hbeat>90

thank you friends for your very good advices 
as a matter of fact i want to program a pic16f877a for a project to measure heartbeat and send sms to the concern doctor (sms include heartrate and location of patient) i want to use sim900 module for sending sms, is it good ?
