Spreadsheet

[Viktoras Didziulis]

Hi David, 
 
regarding the formula processing and scripting, in one project I am using
sqlite to store and process tables because the SQL92 standard supports
things like as well as all major mathematical operators: 
 
SELECT a, b, 
CASE WHEN a>b AND a>2 THEN 'a is greater' 
WHEN a=b THEN a+b 
WHEN a<b THEN 'b is greater' 
ELSE 'unknown' 
END 
FROM mytable; 
 
SQL95 standard brings SQL even closer to complete programming languages, but
it is not yet implemented in litesql which however and luckily is (almost)
SQL92 compliant. 
 
Anyway I see this as the only way to implement any scripting and formula
translation in Revolution, otherwise your end users are likely to smash into
the infamous scriptlimit which is 10 lines of Revcode. 
 
All the best! 
Viktoras

I am just starting work on a basic spreadsheet in Rev - I have a few 
fragments but was wandering if anyone has some work they would be willing to

share? 
 
The bits I have: 
 
1. altTable like component with headers 
2. data model 
3. bits to read and write to OpenOffice documents 
 
I don't have any GUI or code for viewing, adding and editing formulae, or a 
general way of taking standard formulae and applying them to cells. Any 
ideas?
