I've greatly expanded my mini-spreadsheet.

Run it with this command:

gforth sp.fs -e main


- S. Fisher

The 'h' key (help) outputs:

  ;  Copy a cell.                        [  Paste cell and move down 
  ]  Paste cell and move right           \  Paste cell and auto-move 
  c  Recalculate                         C  Toggle compiled formulas 
  p  Print to html file 
  d  Set decimal places for column       ,  Toggle commas for column 
  j  Set justification for column        w  Set width of column 
  m  Set auto-move direction             ^  Lock or unlock rows 
  HOME     Page left                     <  Lock or unlock columns 
  END      Page right                  
ESCAPE commands: 
  q  Quit                                s  Save 
  l  Load                                 
  b  Mark start of block                 k  Copy block 
  K  Copy and clear block                p  Paste block 
  x  Clear current column                y  Clear current row 
  RIGHT or LEFT   Move column right or left 
  UP or DOWN      Move row up or down 
Use ' to start a label. 
Use = to start a formula.  NOTE: all operators have equal precedence, so
  use parentheses to control evaluation order.  A colon (:) is used to sum a
  rectangular area; the formula "=a0:c2*4" sums 9 cells and multiplies by 4.
  Prefix cell-reference with $ to make it absolute (unchanged when pasted).
