AppendTo

AppendTo(s, item)

append item to value of s and sets s to the result.

Examples

>> s = {}
>> AppendTo(s, 1)
{1}

>> s
{1}

Append works on expressions with heads other than List:

>> y = f()
>> AppendTo(y, x)
f(x)

>> y
f(x)

{} is not a variable with a value, so its value cannot be changed.

>> AppendTo({}, 1)
AppendTo({}, 1)

a is not a variable with a value, so its value cannot be changed.

>> AppendTo(a, b)
AppendTo(a, b)
