EQUAL

Purpose:

Determines if two expressions are equal.

EQUAL(val1, val2)

val1	-	A scalar, series, or table.
val2	-	A scalar, series, or table.

A scalar, series, or table containing a 1 when the condition is true and 0 when the condition is false.

equal(W1, W2)

returns a series containing a 1 for every observation where W1 is equal to W2, or a 0 if they are not.

equal({1, 5, 3, 2}, max({1, 5}))

returns a series {0, 1, 0, 0}.

This is equivalent to:

{1, 5, 3, 2} == max({1, 5})

The == is the operator equivalent of EQUAL.
