sc, version 6.21RTR

The spreadsheet calculator sc is based on rectangular tables much like
a financial spreadsheet.  When invoked it presents you with a table
organized as rows and columns of cells.  Each cell may have associated
with it a numeric value, a label string, and/or an expression (formula)
which evaluates to a numeric value or label string, often based on
other cell values.  Formulas may contain invocations of external programs.

sc has builtin mathematical and financial functions.
