Resizing and Deleting Arrays

I've completely forgotten how to resize an already existing array, as well as delete/release/free existing arrays. Any help is appreciated, thanks. |

Deleting an array, just like any other object, is as simple as setting the variable to Null. See MaxIDE Help > Language > Slices for resizing. |

From the help: (help -> language -> advanced topics -> slicing)Local a[200] 'initialize a[] to 200 elements a=a[50..150] 'extract middle 100 elements of a[] a=a[..50] 'extract first 50 elements of a[] a=a[25..] 'extract elements starting from index 25 of a[] a=a[..] 'copy all elements of a[] a=a[..200] 'resize a[] to 200 elements |

Which is fine when you are dealing with a single array dimension but it get's confusing when you need multiple dimensions, does slicing work for multiple dimensions e.g.Local a[200,200] a=a[50..150,50..150] 'middle 100,100 element of a[] a=a[..50,..50] 'extract first 50 elements of a[] a=a[25..,25..] 'extract elements starting from index 25 of a[] a=a[..,..] 'copy all elements of a[] a=a[..200,..200] 'resize a[] to 200 elements ? |

...does slicing work for multiple dimensions[?] No. |

does slicing work for multiple dimensions e.g. No -- I just tried it, and got the following error: "Slices can only be used with strings or one dimensional arrays" |
