Description::
Purpose:
This Vi was made so that you can easily view and create environment variables from within Windows XP.
Features:
You are able to read all environment variables which you have available to you at the command prompt by typing "set". It also can write environment variables by writing them to the registry in the following location:
HKEY_CURRENT_USER\Environment
Also for added safty it will check the name you are trying to use, and won't allow its creation if a variable with that name already exists.
Usage:
To use this VI you need to be using Labview version 8.20. With Labview 8.20 installed open the VariableReadWrite.vi file, then click run. While it's running open the View Variables tab and click "Refresh Variables" to view all your command prompt variables.
Two String arrays are created, the Name of the variables, and their values. A text window is also displaying what the user would see if they typed "set" at a command prompt.
To create a variable open the Create Variables tab and fill in the information for Variable Name and Variable Value; then click Create Variable. Please note that you may need to log off then back on for the new variable to take effect.
If needed there is a "Run Regedit" button which will open the registry. From here you can see the newly created variables in the location mentioned in the Features section.
When you are done click stop to end the program.

Description:
Lists the paths of all VIs in memory other than itself, with the (optional) exception of vi.lib VIs. Note that if you do not exclude vi.lib, some of this VI's subVIs will appear on the list. Prompts user to save the list to a text file or to Cancel the save operation.
This VI might be useful to those who do not use a rigorous source code control scheme, but still want to keep track of many VIs.

Random permutation

Description::
This SubVI takes a positive I32 integer n as input and generates a uniformly random array of the integers from 0 to n-1 as output. It is equivalent in function to the ‘randperm’ command in MATLAB. If a non-positive value is provided, an error is raised to alert the caller.
Version History:
1.0.0:
Initial release of the code.
1.1.0:
Added input validation, error handling, and the option to use "MATLAB mode" and generate a permutation of the integers from 1 to n instead of 0 to n-1, where n is the value wired to the size input. Added a "convert to I32" before feeding the random index to the array functions to eliminate two coercion dots. Updated description to reflect these changes. Changed wiring pattern to 4-2-2-4 and changed icon to accomodate additional terminals.
2.0.0:
Added a random seed input to allow the user to optionally seed the random number generator to produce a specific random permutation. The VI now uses the Uniform White Noise PtByPt function which is not available in the LabVIEW Base package. Users who have the Base package may need to use version 1.1.0 which is still included in the distribution.
