Writing Null Values to a File

What's the best way to write null values in file, then read them back from file?

If you are using the built-in PowerBuilder functions to read the data back (e.g., in ImportFile or ImportString), then the word null in text stream should make a null within the column inside the datawindow. If you are coding this yourself, then you again can use the word null and trap it in your code. Write out the text string of null then wrap the null in quotes (i.e. "null").
