you use VAR because you want to get the pointer to the array, instead of copying the whole array to the procedure’s stack.
so the suggestion was that if you want to make sure the array won’t be modified, you use “-” mark.
what about optimizations, they say, that in principle compiler can understand that you did not write to the passed array, and instead of passing it to the procedure by value (by copying the whole array), pass it by reference (by copying only pointer to it).
i disagree, because i believe, it is important to mark your intentions. if you intent to make sure you pass it read-only, you pass it with “-”, if you intent to pass it read-write, you pass it just with VAR. passing with ‘OUT’, when you cannot read it, but can only write to it is not supported in Oberon.

Here’s a great example of the problems with having only a few red pixels from an outing a few years ago, comparing a Canon 5D Mark II with 4×5 Velvia. Obviously the 4×5 Velvia has more resolution but we downsampled it to match the 5D Mark II and got the following result (show at 200%)
On the right (the 4×5 image downscaled) we can see all of the berries on the tree but on the left (the Canon 5D Mark II image) a lot of the berries have disappeared. The only berries shown are where there were larger groups of them (i.e. a single pixel size berry is unlikely to match up with a single red pixel whereas a group of berries covering 2×2 sensor pixels will definitely hit a red filtered one).
