How can I resize and lock a window?

I am writing a program which is to resize and lock the window. I used resize command, but it doesn't work in the Linux lab. I don't know why, and I also don't know how to lock the terminal window. Can you help me?
For the output to work, it needs to be evaluated as part of the command line, as resize prints a shell command for setting the Term/Termcap env variables. Try setting up an alias:

For example:

alias res 'set noglob; eval `resize`'
Then type in res.

Regarding you wanting to lock your window, take a look at this open source utility that might help you, aptly named lock: http://www.steve.org.uk/Software/lock/
