mathscript node: an internal mathscript error has occurred: 64-bit LabVIEW 2009

[DonRoth]

Hi Folks -

I have an installation now of LabVIEW 2009 9.03f, Vision, and Advanced Signal Processing Toolkit, all 64-bit versions on a new computer so that I can convert some code from 32- to 64-bit.

I figure I will address errors one-by-one and here's the first one.  I have a VI with a mathscript node and the VI, which loaded and ran fine in the 32-bit environment, is now broken and giving the error "mathscript node: an internal mathscript error has occurred."  My main concern - is mathscript not supported in 64-bit LabVIEW right now?

I am attaching the VI.  Any ideas are appreciated.  I need to get this working.

Also, NI, is there a special 64-bit forum that we should post to in the future, or create to post to?

Sincerely,

Don

From 2009 help

LabVIEW MathScript is a text-based language you can use to write functions and scripts. You can process scripts using LabVIEW MathScript in the LabVIEW MathScript Window or a MathScript Node. When you create a LabVIEW MathScript, you must use supported data types.

The MathScript syntax is an intuitive and logical syntax predominantly based on standard mathematical and computer programming terms, terms in widespread and common use, and/or descriptive abbreviations, truncations and concatenations of standard terms. The LabVIEW MathScript Window and MathScript Nodes are able to process files you create using the current MathScript syntax and, for backwards compatibility, files you created using legacy MathScript syntaxes. The LabVIEW MathScript Window and MathScript Nodes also can process certain of your files that use other text-based syntaxes, such as files you created using the MATLAB® software. Because the MathScript RT Module engine is used to process scripts in the LabVIEW MathScript Window and MathScript Nodes, and because the MathScript RT Module engine does not support all syntaxes, not all existing text-based scripts are supported.

(LabVIEW 64-bit) LabVIEW MathScript is not supported in LabVIEW (64-bit).

Yes, and I see that mathscript is no longer even a part of the Professional Edition of LabVIEW 2009 (even in 32-bit).

So, in the near term, we will have to rewrite these scripts in LabVIEW, or C.

Does NI expect to port mathscript to 64-bit soon?

You can suggest something on this on the idea exchange and see how many of them want it too.

Was actually just looking at this (because I suggested this already for the Advanced Signal Processing Toolkit, and NI has come out with an alpha 64-bit version of that primarily at my request).

See the idea exchange thread

and note that user MAGMA has already in a way expressed the Mathscript 64-bit issue with his post which I seem to had forgotten about:

"I've just finished installing the 64-bit version of LabVIEW 2009 under 64-bit Windows 7 Professional.  However as noted above very few toolkits and modules are available for this version. Some of those MIA include MathScript, VI Analyzer, Advance Signal Processing Toolkit, etc. I realize development and testing takes time but think it's reasonable to ask that NI put up a table or chart of toolkits and modules clearly showing which ones are available/compatible with 64-bit LabVIEW, as well as timelines for when these will be available."

And in fact NI responded to this with the table:

For Mathscript, there is no indication of a true 64-bit port anytime soon.  I suppose I should have researched this more carefully earlier.   i was mostly concerned about Vision and ASP 64-bit toolkits, and I forgot about mathscript.

Sincerely,

Don
