Program flow control and constants

[astus]

Hi,
I'm having a problem with an if statement. The evaluation of the if condition is incorrect. The code is below

long int egt;
#define START_TEMP_MAX 80L

egt = read_adc();
if( egt > START_TEMP_MAX ) {
para[ TURBINE_STATUS ] = ERROR_MODE;
para[ ERROR_CODE ] = TOO_HOT_FOR_START;
break;
}

When simulation the if condition is always false as the statement code is never executed.

The code will work if the constant START_TEMP_MAX is assinged to an integer then tested in the if statement. This is a little confusing?

Thanks

It works for me with a 16F877 and PCM vs. 3.178 (in simulation).
What PIC and version are you using ?
