AppDeveloper How to use CSV read/write

[stefan.erni]

Hi Ben

Writing a file works perfectly, if I use delay

reading doesn't go so well

I don't know exactly how to use CSV read/write.
Writing a CSV file works well with the next row command.
But when reading the CSV file, I don't know if I need the command.

Sometimes when creating and writing the file, I end up with an empty file.
If I already have an empty file, then it works fine when I start the program a second time.
I don't know where I need to wait.

Sometimes I still get a lot of 000000 if I open it with notepad.

One command gets stuck readAsNumber(1,0) but the others work.

Hi Ben

I have written a file that generate 10 files and some with extra long filename.
A problem is with the simulation speed.
Can I set it always to full speed?
So I'll start testing “reading CSV into an array.”
The file I need to read has about 12,000 lines.

If this is on second place and the file is small, there is a problem

If this is on first place

it's perfect without a delay and short or long files are ok

With the lot of zeros it's just write number a problem, write int and write strg is ok.
I think it's because of write float (and not a problem).
