Increasing the size of an array works OK if you do this:


But this fails:


It's an easy enough work-around but it would be nice to have both methods work without error.

That is as I would expect it and it is not a bug.

In is an unusual use of the 'inc' command. The command is expected to be used against a numeric variable.

The '.length' of an array is not a normal variable. It is a special object associated with the array that the compiler treats differently. The command to grow or resize an array by changing this value is a special case.

I don't think I know of any language that uses the array.length type object/construct that would allow you to use it with an inc command.

(Usual disclaimer, I didn't create this language or compiler. Maybe the developers of this combination did mean to allow that and didn't code for it. But I have my doubts about that.)

Cheers,

inc is for atomic variables that do not have side effects.

because basic use only integer and float i would expect inc works with this array syntax too.
its more a missing feature.

Yes, "missing feature" is a better description. I wasn't happy calling at a bug as nothing is broken but regardless of how things behave in the background, the average user would expect to be able to use INC in this way.

btw instead of inc or a=a+1
you can use also this syntax
myArray.insert(1)
