Dear all:
Thanks a lot for your kindess. Thanks a lot for Corion's modification.
I never do this mistake again.
I ever used Rpanman's right regexp to test again. However, the problem still is existing!
As for cub's recommendation, I have surfed your website, but I do not know where it is useful for me.
Could you give more hints?
Comment on Re: The problem about the module-"Net::telnet"
cbu, not cub, but that aside. My site serves you with prebuilt recent perl binary depots for HP-UX 11.00, the system you are on. Both HP-UX 10.20 and HP-UX 11.00 are not supported anymore by HP, so you won't be able to get recent perl builds from them.
