This Kind of Array Cannot be Sorted

Error message

You tried to sort a Boolean array or an array of objects.

Examples

You tried to sort an array of objects instead of an array of alphas or numbers. For example, an array of DateTime objects cannot be sorted, but an array of SecondsFrom1970 properties of DateTime objects can be sorted, since the SecondsFrom1970 property is a Double.

This example array cannot be sorted.

Var d(2) as DateTime
d(0)=New DateTime(1965, 1, 1)
d(1)=New DateTime(1970, 1, 1)
d(2)=New DateTime(1950, 1, 1)
d.Sort

The last line of this example produces the error message.

Var theTruth(3) as Boolean
theTruth(0)=True
theTruth(1)=True
theTruth(2)=False
theTruth(3)=False
theTruth.Sort
