Multi-dimensional spreadsheet system enabling stack based programming using a virtual machine

A combination programming environment using spreadsheets is described that supports stack based sequential program execution using spreadsheet cells supporting recursion, reentrancy, conditional blocks, loops and block based dependency execution using a virtual machine. This is achieved by partitioning cells in any sheet into named blocks and unnamed blocks that are executed using conditions. Named blocks can be arranged in a call sequence with a caller cell setting up a call to a callee named block using the name of callee block in caller cell formula.
