Hi Chris,

In MWorks, how does the equality operator work for lists, does it do deep comparison?  
For example, are all of the following reports correct below?

Mark

* * *

var ab = [1,2,3]  
if (ab == [1,2,3] {  
report(‘hopefully true’)  
}

var ab = [‘a’, ‘b’, ‘c’]  
if (ab == [‘a’,‘b’,‘c’] {  
report(‘hopefully true’)  
}

if (ab == [1,2,3] {  
report(‘hopefully false’)  
}  
if (ab == ‘astring’ {  
report(‘hopefully false’)  
}

Hi Mark,

Yes, equality comparison is always deep, for both lists and dictionaries. All of your examples work as you expect.

Cheers,  
Chris
