I am trying to make a program in mplab ide v8.66 for pic18f458 using c18 v3.37.01.

To do so, I have gone through the steps told in this video

https://www.youtube.com/watch?v=84Tu4eLTLVY

the code is below:
//-------------------------------------
#include <P18f458.h>
void main (void)
{
TRISB = 0;
for(;;)
{
portb = 0x55;
portb = 0xAA;
}
}
//-------------------------------------

the output file shows:
----------------------------------------------------------------------
Debug build of project `D:\picassemblyprojects\fuzoolC.mcp' started.
Language tool versions: MPASMWIN.exe v5.40, mplink.exe v4.38, mcc18.exe v3.37.01, mplib.exe v4.38

Code:
#include <P18f458.h>
void main (void)
{
TRISB = 0;
for(;;)
{
PORTB = 0x55;
PORTB = 0xAA;
}
}

portb should be in uppercase... that's why the error states that it doesn't know what is 'portb'


don't forget to set the configuration bits for real implementation...
