Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

Using Codesys 3.5.18.30 I am trying to work with an array of variable length in one dimension, but known in the other dimension. For example, using an array that represents a list of items, each with an attribute profile. I do not know how many items will be in the list, but I know that every item has 5 attributes, like size, weight, etc. Codesys does not seem to be able to accept this. I have referenced Data Type: ARRAY OF documentation page, which is not explicit if variable & fixed length array dimensions can be mixed. In the VAR_IN_OUT scope, I initially tried MY_ARRAY : ARRAY [*, *] OF REAL; which was no problem, of course. I then modified it to MY_ARRAY : ARRAY [*, 1..5] OF REAL; which throws C0006: ', or ]' expected instead of '..' among consequent downstream errors. I then used the Auto Declare -> Array Wizard, which accepted (asterisk)-(asterisk) and 1-5 for 2-dimensional lower and upper bounds. It output: MY_ARRAY: ARRAY[*..*, 1..6] OF INT; which throws the same error stream. What's the deal here? Is this possible?
