 		 #61455 - RE: c51 if validation
Responding to: ???'s previous message
I didn't understand following 'if ' statement validations...

1. if(test&0x80){}

2. if(test|0x01){}

If the expression within the parentheses evaluates to nonzero, then the statement immediately following the parentheses is executed. So,
  1. If test's bit 7 is set, the statement within the braces is executed.

  2. The statement within the braces is always executed because OR'ing test with 0x01 causes the conditional expression to evaluate to nonzero.
