spreadsheet n 1 :
a screen -
oriented interactive program enabling a user to lay out financial data on the screen (Or rarely "worksheet ") A type of
application program } which manipulates numerical and string
data in rows and columns of cells . The value in a cell can be
calculated from a formula which can involve other cells . A
value is recalculated automatically whenever a value on which
it depends changes . Different cells may be displayed with
different formats .
Some spreadsheet support three -dimensional matrices and cyclic
references which lead to iterative calculation .
An essential feature of a spreadsheet is the copy function
often using {drag -and -drop }). A rectangular area may be
copied to another which is a multiple of its size . References
between cells may be either absolute or relative in either
their horizontal or vertical index . All copies of an absolute
reference will refer to the same row , column or cell whereas a
relative reference refers to a cell with a given offset from
the current cell .
Many spreadsheets have a "What -if " feature . The user gives
desired end conditions and assigns several input cells to be
automatically varied . An area of the spreadsheet is assigned
to show the result of various combinations of input values .
Spreadsheets usually incorporate a {macro language }, which
enables third -party writing of worksheet applications for
commercial purposes .
In the 1970s , a {screen editor } based calculation program
called {Visi -Calc } was introduced . It was probably the first
commercial spreadsheet program . Soon {Lotus Development
Corporation } released the more sophisticated {Lotus 1 -2 -3 }.
Clones appeared , (for example {VP -Planner } from {Paperback
Software } with {CGA } graphics , {Quattro } from {Borland }) but
Lotus maintained its position with world -wide marketing and
support - and lawyers ! For example , Borland was forced to
abandon its Lotus -like {pop -up menu }.
While still developing 1 -2 -3 , Lotus introduced {Symphony },
which had simultaneously active windows for the spreadsheet ,
graphs and a {word processor }.
Microsoft } produced {MultiPlan } for the {Macintosh }, which
was followed by {Excel } for Macintosh , long before {Microsoft
Windows } was developed .
When {Microsoft Windows } arrived Lotus was still producing the
text -based } 1 -2 -3 and Symphony . Meanwhile , {Microsoft }
launched its {Excel } spreadsheet with interactive graphics ,
graphic charcters , mouse support and {cut -and -paste } to and
from other Windows applications . To compete with Windows
spreadsheets , Lotus launched its {Allways } add -on for 1 -2 -3 -
a post -processor that produced Windows -quality graphic
characters on screen and printer . The release of Lotus 1 -2 -3
for Windows was late , slow and buggy .
Today , Microsoft , Lotus , Borland and many other companies offer
Windows -based spreadsheet programs .
The main end -users of spreadsheets are business and science .
Spreadsheets are an example of a non -algorithmic programming
language .
