Me too.

Oh i dunno! Once you start thinking in terms of recursive algorithms you
start seeing them everywhere.

Totally. There is somewhat of a workaround. If you have the Script control
installed you can write recursion in VBS or JScript. It's still no fun
though - just adding the code to a script control instance gets messy.

> Also the need for callback functions.

A great need for Windows interaction. Unfortunately since VEE isn't compiled
there will never be an executable address of anything, but you can kind of
do it. Use the address of a function in an Automation library as the
callback address. Have the library callback function fire an event, and
catch the event with VEE. Not quite the same, but it works.

Hi,
I knew this would come up at some point. The easiest method of creating
combinations is by using a recursive function. However, Vee cannot perform
recursion. Also, the 'Quicksort' method of sorting data also requires
recursion. Please could Agilent make note of this, since when I first
brought this up about five years ago, I was asked by Agilent "Why would you
want recursion?".
You have your answer now, Agilent!
(by the way, I am told that LabView does perform recursion - can anyone
confirm this?)

Regards

Dave

I need to be able to generate all the combinations from this text string

The output is four values comma separated as a text string. This example
should generate the text string array.
The code needs to be able to cope with more values and detect how many
variations there are in each part of the string.

Does anyone have any ideas how to do this?

Yes, it can be done

Go here and do a search on "recursive"
http://www.ni.com/devzone/dev_exchange/ex_search.htm

Go with the link that has the factorial.vi. The way it works is it
calls a reentrant VI dynamically, within itself. I'm still learning
how to use this feature... email me if you want to talk LV

Hello everyone,

I'm new to the list and I would like to avoid dragging out old
topics. Is there an archive or a FAQ for the VRF?

BTW, I was directed to this list from a user on lurkerslab.com

Dang Bill, you beat me to it! I was working on something VERY similar
to your end result, but I think yours turned out quite a bit cleaner.

One suggestion though, in the box: READ TEXT x TOKEN EXCLUDE:"|" ARRAY:*
IF you change the "|" to "|
" you can strip the extra "junk" off.

I must say to all, WELL DONE! This is not the first time someone has hit
the VRF with a problem that was not obvious to solve at first, but after
a few posts started to pop up, the answer slowly came into focus.

What a great group.

BTW Vlad, I guess some of us ARE rather passionate about VEE!

Here's a solution that should handle any number of categories with any
number of entries. It is a generalization of Mike Asberry's solution, and
uses essentially the counter logic that Bill K. described.
