Thanks for that info. I was looking for that info in the wrong guide.
Personally, I do not use ‘Hungarian’ prefixes as a rule unless there is some aspect about the variable’s function and semantics that cannot be inferred from its original type alone, or the prefix adds useful extra information. Of those that you showed, the most likely ones I would use would be the timer prefixes and perhaps the prefixes related to points and handles.
I guess that I am also used to strongly typed languages. On a slightly related note: will OptoScript eventually allow for local variables? It can be a pain not having them though on the other hand it does cut out a lot of bugs related to memory management.
