.SetUpdateOffset

The row and column coordinates on a terminal screen. The offset is zero-based and is the equivalent of the following formula:

offset = [(row - 1) x width] + (col - 1)

The reverse formulas (offset to row/col) are as follows:

row = (offset / width) + 1, where the division operation uses integer logic (remainder of the division operation is ignored)

col = (offset % width) + 1, where % means modulo (use only the remainder of a division operation)

Example: For an 80 column terminal screen:

row 1, col 1 = offset zero (always true)
row 1, col 2 = offset 1 (always true)
row 2, col 1 = offset 80 *(depends on the screen width)
