The EQU instruction doesn't support the LINT data type in any version, as far as I'm aware. I don't think there are many instructions that DO support LINT.
As to the OTL, if you define an INT, DINT, LINT and a REAL in your tag database, you can expand out the INT and the DINT to view each individual bit - but you can't do it with the REAL or the LINT. Given that you can't address REAL bits individually, and the fact that they behave the same way in the tag browser, I suspect the same applies to a LINT.
Side note - I've always wondered why you can't do it with a REAL - it's still 32 bits, and if you're using them for boolean operations the number is just as nonsensical whether you interpret the whole 32 bits as a DINT or a REAL. But in any case, computer says no!
