Well, I found a small font to load into those undersized 3b1 windows.
When I use the vi editor, however, only a limited section of the window
window is used. How can I change the size that the window thinks it is?

How can I change the size that the window thinks it is? You have to change the TERMCAP environment variable in your shell. This defines the number of lines and columns in the window, among other things. Some programs, (I do not think vi is one), also require that the environment variables LINES, and COLUMNS must be made to match the size of the screen. I have written a short program, (which I call sz), which will set these for you. Maybe it's time to clean it up, and post it. Is there interest? A program cannot change the environment of its parent, so you actually type $ eval `sz` -- Tom Tkacik ...uunet!edsews!rphroy!tkacik GM Research Labs tkacik@kyzyl.mi.org "I'm president of the United States, and I'm not going to eat anymore broccoli." --- George Bush

How can I change the size that the window thinks it is? There are two different systems programs use for determining window size: terminfo (System 5) and termcap (BSD). The Unix PC has both; some programs that come with the system (e.g. more) use termcap and other programs use terminfo. Both of these systems use the environment variable TERM to determine the terminal type; each terminal type has a terminal description, stored in /etc/termcap (for termcap) or in /usr/lib/terminfo/*/* (one file per terminal) for terminfo. The terminal description specifies the screen size. Thus it is possible to change your window size by making one terminal description for each size you want. This is a pain. Both termcap and terminfo have ways to override the size in the terminal description. For terminfo, you set the environment variables LINES and COLUMNS. For termcap, you set the environment variable TERMCAP. TERMCAP can be set to a name of a file, in which case termcap looks in that file rather than in /etc/termcap for terminal descriptions; TERMCAP can also be set to a terminal description. So to resize your window, set your environment up with: LINES=24 # or whatever COLUMNS=80 TERMCAP=vs|xterm|vs100|xterm terminal emulator (X window system): :cr=^M:do=^J:nl=^J:bl=^G:le=^H:ho=\E[H:cl=\E[H\E[2J: :bs:am:cm=\E[%i%d;%dH:nd=\E[C:up=\E[A:ce=\E[K:cd=\E[J:so=\E[7m:se=\E[m: us=\E[4m:ue=\E[m:md=\E[1m:mr=\E[7m:me=\E[m:ku=\EOA:kd=\EOB:kr= \EOC:kl=\EOD:kb=^H:k1=\EOP:k2=\EOQ:k3=\EOR:k4=\EOS:ta=^I:pt:sf=\n:sr=\E M:al=\E[L:dl=\E[M:ic=\E[@:dc=\E[P:MT:ks=\E[?1h\E=:ke=\E[?1l\E> :is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;3;4;6l:rs=\E[r\E<\E[m\E[2J\E[ H\E[?7h\E[?1;3;4;6l:xn:AL=\E[%dL:DL=\E[%dM:IC=\E[%d@:DC=\E[%dP: :ti=\E7\E[?47h:te=\E[2J\E[?47l\E8:hs:ts=\E[?E\E[?%i%dT:fs=\E[?F:es :ds=\E[?E:li#24:co#80: # replace this with a unix pc termcap entry # and take out the newlines export LINES COLUMNS TERMCAP I am aware of two programs that get the current window size and set up these variables; one is called "sz" or "rsz" or something, and the other is my "wind" program, a small command interpreter which opens windows and runs processes in them. -- Norman Yarvin yarvin-norman@cs.yale.edu
