Write a string and an integer and a table all in the same file?

Hello

I am currently it several different types of values with LabView.

I have a shot, a few numbers and several paintings.

Thus, for example, I have a timestamp of the chain, several values of "integer" amplitude of the signal for example, RMS value, frequency and I have several paintings - table of signal, the FFT (PIC and location) values.

Basically, I'm trying to find a way to write all the values in a single file. I can write all the individual types to separate files (so I can write the RMS, amplitude and frequency to a single file, some of the tables in the other)
but is it possible to write a string and an integer and a table all in the same file?

Pointers would be much appreciated,

Thank you

Paula

Your file will be all text... any format in a table of text, to build as a single table, "table chain worksheet", to write to the file.

(I'm sure this has been on the forums before... a search it would have thrown upward)

		     How to record the numbers and words in the same file 
			 Hello:
I did a vi where I record the spectrum and its integration in different positions of a two-dimensional net. I save the information in two spreadsheet with the comand "write to file measure."
Now, I am recording the parameters initial positions, end X X and space between measurement points. I want a file with two columns that looks like:
Initial position X 1000
final position X 2000
space 100
But idon't know how to save the words and numbers in the same file.
As I have to perform several steps I want to automatically choose the name of the file (something like parameters_1, parameters_2...)
Thank you for your attention
			 Hi bitxor.
You can use all the functions of the WriteTotext file to write strings to a file.
Then you could set up WriteToMeasurementFile' to add new data to existing files (instead of overwrite or renaming)...
BTW. It is not a good idea to mix lvm files containing arbitrary spreadsheet data!
