Dear all, Thank you for your help in advance. I created a very simple program to test my Monitor-51 which is showed below:
#include "AT89X55.H" sbit P25 = 0xA5; void DELAY(int j) { int i; for(;j>0;j--) { for(i=2;i>0;i--) {;} } } main(){ while(1) { P25 = 0; DELAY(1); P25 = 1; DELAY(1); } }

Why does my program always start from C:0x00AE? This question reminds me of a Peter Sellers movie. A man asks an innkeeper, "Does your dog bite?" The innkeeper said, "No." The man leans over to pet the dog and the dog nearly eats his hand off. He turns to the innkeeper and says, "I thought you said your dog did not bite." The innkeeper responds, "That is not my dog." I guess my smart-aleck answer to "Why does my program always start from C:0x00AE?" is, "That is not your program!" Jon
