错误处理!!
1:在一个程序中,p1包含语句resume next,而p2没有错误处理代码,如果p1调用p2,并在p2中产生一个错误,会有什么情况出现??
a:the error is not trapped because p2 containsno error_handling code!
b:the error_handling code in p1 is invoked and the call to p2 is re-executed
c:the error-handling code in p1 is invoked and the line in p1 following the call to p2 isexecuted
d:the error_handling caode in p1 is invoked and thelinein p2 following the error is executed
