Array in an array

[Kernelpanic]

Again to static and dynamic array.
A static array is assigned a fixed, immutable memory location when compiled by the compiler. This can neither be deleted (Erase) nor re-dimensioned. The Erase command just reinitializes the array new with zeros.

In the case of dynamic arrays, the storage space is not determined until the program is running, so it does not have a fixed storage area. Therefore, a dynamic array can also be re-dimensioned with Redim (Erase & Dim): A 4 * 4 array can become a 4 * 6 array, but the dimensions must be observed. A two-dimensional array cannot become a three-dimensional one.

If only the Erase command is applied to a dynamic array, then it no longer exists because it has no a fixed memory area, so it was really deleted, so nothing can be seen anymore.
