a more generic xl_inc_row (and related)?

[Terrence Brannon]

I had a need to write the same class of data at 3 places in a spreadsheet. However, there was no function to take a certain cell and provide an arbitrary row-increment, only 1.

Before submitting a patch, I wanted to discuss my need for this and see what others thought.

Here is the function I am using for my purposes:

sub my_xl_inc_row {

  my($cell, $inc)=@_;

  $inc //= 1;

  my ($row, $col, $row_abs, $col_abs) = xl_cell_to_rowcol($cell);

  return xl_rowcol_to_cell($inc + $row, $col, $row_abs, $col_abs);

}
