Query: Changing # of display lines (terminal capability)

[Kingsley F. Kerce]

I'm interested in setting my terminal capability to allow 42 lines
(rows) of text before scrolling occurs while using vt100 emulation.
What does this require?

I've attempted the following:
	-Copy important parts of /etc/termcap to ~/termcap and modify
	 the vt100 entry to read ...:#li42:...
	-`setenv TERMCAP ~/termcap' in .login (after `set term=vt100'
	 and `setenv TERM vt100')

The above attempt had no effect as far as my shell is concerned
(tcsh)--it still scrolls at 25 lines.  GNU Emacs liked it to a
certain extent--it shows 42 lines, but shows erratic behavior when
scrolling occurs.

Any suggestions would be much appreciated.  Please email if possible.
Thanks,
