I get an error :

'$' is not a valid integer value

while loading ledtest.hex (for LED blinking )on 89c51 ( based on tutorial at http://www.proaxis.com/~iguanalabs/1stmicro.htm )

I'm using Easy-Downloader V2.0 for ATMEL 89C51/52/55
programmer for 89c51 ( http://chaokhun.kmitl.ac.th/~kswichit.../easy2.htm )

the content of ledtest.hex is as follows
