请看下面两段PERL程序
仅仅KEYS不同，而结果不同。
#! /usr/bin/perl
%array1=(1,"111",2,"222",3,"333",4,"444",5,"555",6,"666"

;
@array2=values(%array1);
print("%array1:"

;
print($array1{1}," ",$array1{2}," ",$array1{3},"\n"

;
# print("@array2:"

;
print ($array2[0]," ",$array2[1]," ",$array2[2]," ",$array2[3],"\n"

;
的结果是：%array1:111,222,333
111,222,333,444

#! /usr/bin/perl
%array1=(one,"111",two,"222",three,"333",four,"444",five,"555",six,"666"

;
@array2=values(%array1);
print("%array1:"

;
print($array1{one}," ",$array1{two}," ",$array1{three},"\n"

;
# print("@array2:"

;
print ($array2[0]," ",$array2[1]," ",$array2[2]," ",$array2[3],"\n"

;

的结果是：%array1:111,222,333
111,555,333,222

请指教！WHY！

个人认为hash是无序D

应该是无次序的。UNIX下毕竟不象VC下有很多BUG。
在此谢谢楼上的。我RETRY
