    I'm not sure if this is possible or not. I have read through logic dox and piced dox and can't figure out how to do it - maybe because its not possible? Easiest to explain what I want to do: I have GIU that measures a water tank level and broadcasts in litres i.e 24,500. I am happily displaying this on my CTC and using several side by side sliders to represent the tank level % - looks cool. All good so far and works fine. What I want to do however is display the last 30 days history on the CTC. The routine to write the date and measurement to file is easy enough. And I can read the data back from the file easy enough. How do I get the historical data into a table on a page though. I can't figure out how to write a value to a text object. i.e what is the command? I do a lot of VB OOP and normally the text object/component has a property that can be written / or read using code....can piced pascal do something similar? Maybe there's another way? thanks if any one can help.

    If you just want to write a string to the screen from logic. Use a string type system IO variable, and create a component to monitor the status of this variable on the page.

    You write to the string system IO using SetStringSystemIO();

    Is this what you were after?

    If you want to dump a lot of text on the screen on the CTC, I think you can also use the DrawText() function to write directly to the screen.

    write system IO

    thanks Nick!
    thats two ways to do it. I guess given its 60 variables probably better to write a draw table function and drop the read file array into it. Much appreicate the pointer. cheers.
