SpecialExpReturnNull (Magic xpa 3.x)

This flag maintains backward compatibility when comparing a variable that has a Null value to an empty value.

In uniPaaS 1.9, comparing a variable with a Null value to a blank string or to zero, returned a False value and the rest of the expression was ignored. For example, the expression of ''A<>'' or 'True'Log '' (where A has a Null value) returned a False value since the rest of the expression after the comparison was ignored.

From Magic xpa 2.5 onwards, the expression of ''A<>'' (where A has a Null value) returns a True value.

Setting this flag to Y simulates the uniPaaS 1.9 behavior.

Setting this flag to N performs the correct calculation as per Magic xpa 2.5.

Valid values: Y,N

Default value: N

Since version: 3.1
