      Here is the Hooovahh Array VIMs.  This initial release contains VIMs for manipulating array data, which are intended to replace OpenG functionality, but with the added benefit of data type propagation, and increased performance using newer array manipulation techniques.  In later versions other Array manipulation functions were added moving all the OpenG stuff to their own palette. 
      Version 2.0 changed the suffix naming standard.  Updating may mean replacing calls to the new versions since the name on disk has changed.  This was for consistency and I'm sorry for breaking compatibility.  The added type defs in 2.0 may break compatibility too but these help avoid code breaking bugs since VIMs allowed any data type previously.
      Most of the OpenG functions are unchanged, but a few use the newer conditional and concatenating tunnels.  And a few functions have added performance based on other inputs.  For instance the Delete Array Elements can operate in a more efficient way if the input indexes are already sorted.  The Filter 1D array can also be more efficient if the input is known to not contain any duplicates.
      Because these packages contain VIMs, they require LabVIEW 2017 or newer.  Having these functions be VIMs mean all functions work with various array data types.  Included functions are:
      Conditional Auto-Indexing Tunnel Delete Elements from (1D or 2D) Array Filter 1D Array Index (1D or 2D) Array, Scalar, Row, Column Remove Duplicates from 1D Array Reorder (1D or 2D) Array Reverse 1D Array Slice 1D Array Sort (1D or 2D) Array Convert 1D to 2D Convert 2D to 1D Find Subarray Force Array Min/Max Size Foreign Key Sort

      For those who have been playing with malleable VIs, the Type Specialization Structure has probably become a common sight and much abused tool.
      The basic use of it is that if the action it performs is meaningless given one of the inputs, the included code will break and the next case will be tried.
      This is great, but sometimes, it can be difficult to think of all possible variants of an action, and in particular, if the action needs to be different for two or more types, but two or more types are compatible with different codes, how to make sure which code will be executed with what type?
      Enters the Types Must Match function:

      I found this little gem in... Hidden Gems, within an odd-looking VI which I felt compelled to check out, Debug Write.vim

      Open its diagram and light will shine, opening grandiose vistas and parallel universes remaining to be explored.
      Of course, as the comment on the diagram says:
      "This structure and the type-testing primitive functions it contains are not public LabVIEW features. They are experimental and should not be edited, copied, or used in other VIs without conducting extensive testing. See Context Help for details."
      Here is the context help for Types Must Match:

       
      My apologies if this all well-known among expert users, but I couldn't find it mentioned otherwise on the site...

      After reading this LabVIEW Idea exchange request:
      http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Provide-a-better-way-to-implement-a-polymorphic-VI/idi-p/920487
       
      I was inspired to create VI macro(s) to attempt to address the problem mentioned in the request.  Attached is my first attempt and I'm looking for feedback since I know people here have strong opinions.   The benefit of this method is that a single vim (or 2 could replace a polymorphic VI with over 48 separate VIs....unless I'm missing something.  I know that VI macros are not officially supported by NI, but that hasn't stopped us from using unsupported features before.  Some people have probably already done something like this, but I couldn't find an example.
       
      To use the files, unzip them and copy them all to your \LabVIEW (version)\user.lib\macros\ directory.  
      Create the directory if it does not exist.  For example: C:\Program Files (x86)\National Instruments\LabVIEW 2014\user.lib\macros\   And as described in the wait-ms-with pass through post below, modify your LabVIEW.ini file to have the following     ExternalNodesEnabled=True and Optionally     XNodeWizardMode=True   http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Wait-ms-with-error-pass-through/idc-p/3178218#M31820
       
      Open the Example Changed.vi and review.

      This is an experimental demo to investigate VIMs (vi macros). It was a bit of fun to see if VIMs could be used to encapsulate events in LabVIEW which was a bugbear of mine for quite some time. You can see the entire thread here. VIMs are a NI experimental technology similar to Xnodes but less mature.
       
      The purpose of this release is to clarify the previously unstated licence since other forum topics are building on the original demo so they need a permissive licence (MIT). This release serves as an unambiguous statement to that effect. There are a few differences from the original which I have decided to call version 0.1 but they are minor.
       
      Note:
      This may or may not work for you out of the box. If it doesn't then please do not post. The purpose is to clarify the licence for others to build upon; not to provide a working example. The VIM technology is itself  experimental and unsupported by NI so most issues you will encounter will be due to this and It is unlikely there will be another version posted here.
