•

In a list variable, a cell in the gap is undefined until you enter a value for the cell.

Note:

If you enter more than one column of elements in a list variable, it is converted

automatically into a data variable.

•

In a data variable, gaps in a column are handled the same as a list. However, if you
leave a gap between columns, that column is blank.

•

In a matrix variable, when you enter a value in a cell outside the current boundaries,
additional rows and/or columns are added automatically to the matrix to include the
new cell. Other cells in the new rows and/or columns are filled with zeros.

Note:

Although you specify the size of a matrix when you create it, you can easily

add additional rows and/or columns.
