Write CSV file

[rscott]

When using the WriteCSV() function

At what point does mathcad actually write the file?

When you close the program

Periodically? 

How do you force it to update the CSV file?

Thanks in advance

Mathcad generally writes data to file upon execution of the statement that implements the write function (similar for read).

Once written, there is no need to write again (Mathcad is lazy). If your data is updated and you need it written out again, make sure the statement gets executed. Generally this is accomplished by putting the cursor on the write statement en pressing F9.

Success!

I still cant get this to work.

Mathcad will NOT update this file. 

I dont get. 

No matter what i do or dont do it will not update. 

F9 appears to do nothing. I have opened and closed mathcad. I have deleted the CSV and tried to force it to recreate it.

It will not do push the new data. This is a simple Colum vector. Can someone please lend a hand

Maybe you should attach the Mathcad sheet...

Attached is an example, Prime 4:

Put the cursor on the runif function and press F9.

Observe that Data changes, as does the output of the WRITECSV function. It means that the data was written.

Put the cursor on the READCSV function and press F9.

Now the READCSV function executes and reads the data back from the file.

Success!

I got it to work

I found the answer in an old thread that involved WRITEEXCELL

if you do something like

RESULT := WRITECSV(.......) 

It will work

You cant just do

WRITECSV(....)
