Warning 203 "test.c" Line 10(1,1): Condition alway

Why!
Tell me.

#include <16F877.h>
#fuses
#use delay(CLOCK=20000000)
#fuses HS,WRT,NOPROTECT,NOWDT
#include <lcd.c>

main(){
lcd_init();

while(1){

lcd_putc("message001");
delay_ms(1000);
}
}


Deleting intermediary files... done.

:=Why!
:=Tell me.

Because "1" never becomes "0": while (1)
The TRUE state in C means "non zero".

These are just typical precautionary warnings that many compilers issue to make sure you know this was done.

Notice it says "Build Succeeded" which means the program copiled normally.

Another warning you may see is one for unused variables (#202) which may or may not be handy for you. I use it when I am in the "clean up" stages, otherwise I keep it turned off.

To hide these messages put in a line near the top of the code like:

#IGNORE_WARNINGS 202, 203
// turn off Unused Variables (202)
// and Always True (203) warnings

Regards,
Dave
