From the shell:
 
        $#term is already defined.
        $export LINES=40
        $export COLUMNS=132
        $vi foo
 
From the CI:
 
        :setvar term "hp2392a"
        :setvar lines 40
        :setvar columns 132
        :run vi.hpbin.sys;info="foo"
 
These variables are picked up by vi on entry to determine the screen size.
The default is 80x24, but it _can_ be changed.
 
We have a script file that the CI can execute to determine the screen size
and set these variables:
 
        option nolist
        if hpjobtype = 'J' then
           return
        endif
        SETVAR _cur_pos "NOPE"
        INPUT _cur_pos,![chr(27)+"`"],5
        IF '!_cur_pos' = "NOPE" THEN
           ECHO Can not read your current cursor position.
        ELSE
           COMMENT Now read the window size.
           SETVAR _win_size "NOPE"
           INPUT _win_size,![chr(27)+"&a999c999Y"+chr(27)+"A"+chr(27)+"`"],5
           IF '!_win_size' = "NOPE" THEN
              ECHO Can not read your window size.
           ELSE
              SETVAR _win_row "![str('!_win_size',8,3)]"
              SETVAR _win_row "![!_win_row+2]"
              SETVAR _win_col "![str('!_win_size',4,3)]"
              SETVAR _win_col "![!_win_col+1]"
           ENDIF
           ECHO !_cur_pos![chr(27)+"A"]
           SETVAR lines "!_win_row"
           SETVAR columns "!_win_col"
           DELETEVAR _win_size
           DELETEVAR _win_row
           DELETEVAR _win_col
           DELETEVAR _cur_pos
           SHOWVAR lines
           SHOWVAR columns
        ENDIF
 
The shell version is left as an exercise for the interested reader :)

Did you:
 
        setvar hptypeahead true
 
before entering the shell?  I think that helps but I'm not sure about this
particular case.
 
: 25) As many other have noted, more(1) should not clear the screen when
: called.
 
I think there's an SR for this already.
 
: 26) HP should included some non-POSIX extentions found in HP-UX so
: mixed platform HP shops have a more unified environment (ll comes to mind).
 
You can easily do this for yourself by adding to /etc/profile or to your
local profile:
 
        alias -x ll="ls -l"
