After the program is started up you shouldn't need to keep asking
for the whole path name.
The docs on the toggle keys don't seem to match what they do.
Fix the way the graph function returns error, not enough X values
is a very poor way of saying, you need a string not a number label
It should check at runtime for the crypt program since different machines of
the same type may or may not have crypt or DES on them.
It brings up the window OK, but when I type " to insert a string in the
current cell, I get a load of gibberish printed in the current cell. If I
type in a string (say, "Hello"), then "Hello" does get inserted OK into the
cell. It's somewhat disconcerting to see a load of random characters in the
cell before you press RETURN to terminate the string ! This didn't happen
with xspread 1.1 and HP-UX, I hasten to add :-)
I am impressed with xspread, except for one nagging bug. When editing the
contents of a cell, the underline cursor doesn't move. The program's idea
of where the cursor *should* be does change (i.e. you can insert characters
into the middle of the line), but the underline never moves. It does move
while in insert mode, however. This happens under 2.0 and 2.1. I'm running
the generic R5 Xsun server, pl.21.
Currently this is xspread.. One day it will be incorporated
with SC. SC and xspread will be the same program.
I've also noticed that sc.c could not compile if DOINGX is not defined
due to the use of userfont which is declared only when DOINGX is
defined. Some of the other defines also still get screwed up.
BTW, there is a serious bug concerning functions that return strings
(eg @DATE, @SUBSTR): it says "invalid numeric function" or somesuch.
This means that eval() instead of seval() is being called for those
functions, but I couldn't discover why. At present, you can't use
functions that return strings.
- Let the user save the graphics definitions across sessions,
either bound to the spreadsheet or in an standalone form.
I mean a way to suspend work now and be able to return to
it later.
- Graphic option selection user interface needs tuning, ranges
would be the ideal way to define the rows desired. Still
better if TAB works the standard way in sc.
- The mouse is underutilized. It should be possible to select ranges
using the mouse. I use at the office sc with NCSA Telnet and
I can use the mouse of my PC to select ranges. I really miss
that function when using X. Also, it should be possible to
scroll the view of the spreadsheet with the mouse.
- There is also another deficiency that is not particular to
xspread, but rather inherited from sc, and is the lack of
column and row freezing on screen, I mean the ability
to leave some region fized on the view while the rest of the
spreadsheet scrolls. Hiding and showing is not enough.
- Alternatively (or in addition to the above), opening other
views of the same spreadsheet simultaneously.
- Real time update of the graphic from the data, and maybe
several graphics at the same time.
