A scalar is an expression that evaluates to a number, boolean or string.

Any value, function or operation that is or returns a number, boolean or string is a scalar expression.

Examples:
1
1 + 2
avg(Q1)
pctin(Q1,1)
validcount(Q1)

The following are NOT scalar_expressions:
Q1 is not a scalar expression because it represents multiple values: one for each row in a dataset. It is a vector.
nullifeq(Q1, 99) is not a scalar expression because nullifeq would return a vector if the first parameter is a vector (which it is).
