SETPT

Purpose:

Modifies the nth value of a series.

SETPT(series, value, index)

series	-	Optional. Any series or multi-column table. Defaults to the current Window.
value	-	A real, the value used to replace the current value.
index	-	An integer, the point index.

a = {1, 2, 3}

a = setpt(a, 10, 3)

sets the third point in the series a to 10. This is equivalent to a[3] = 10.

An index n refers to the nth point in the series, therefore the new value is assigned to the nth point in the series.

The following array syntax also sets values in a series:

Wn[index] = value

For example: W3[2] = 10.

See .. (Range Specifier) for more array syntax examples.

SETPT is useful when using expressions containing CURR. For example,

W1: 1..8;setpt(curr, 0, 2)

creates the series {1, 0, 3, 4, 5, 6, 7, 8}

W1: 1..8;W0[2] = 0

creates the same series since W0 refers to the current Window.
