Based on the source of My Little Grid, this sample can:
Load / Save Sheets (like excel, but not compatible)
Create Edit/formulas
Change View Mode (Data or Formulas)
Eval Formulas
Get / Set any Cell value (or Formula)
Clear Grid
Sort asc / desc any col
Menu is in NeoBook code, Grid is in thinBasic code.
If you want to set a formula, you must set = (the equal sign) as the first character. The rest is a simple calculation as A3*B5/F4, etc
Sample is not perfect, but is a good begin point to get a ellegant grid.
