All,
How do I output to the same position in a Text file everytime? I want to
output data for a given Date so I'd like to put it in the same row for that
Date everytime, and so overwrite the existing data in that row?

I use the following command:
Write #10, dateline, variable1, variable2, variable3
'where dateline is today's date in excel date code.
I drop into the file at the row corresponding to last week's date e.g. row
40010.
Write #10, dateline+1, variable1, variable2, variable3
'where dateline +1 is tomorrow's date in excel date code.
I drop into the file at the row corresponding to today's date e.g. row
40017.

I want to be able to open my text file, overwrite the existing data in that
file for the row corresponding to today's date. Is it possible to write to a
specific row in a text file..... ?
thanking you
Bernard

You'll have to read it and parse the data, check what you want to determine if
you're on the correct row, and then write out the variables (with the new
value).

And I would suppose you'd want to check to see if there's a matching date record
in your file--then add (or whatever you wanted) that new record.

Hi Bernard,

Someone might be able to answer your question to do this but if not then I
would give consideration to writing it to another Excel workbook with only
one worksheet and then Save the Excel workbook as a text file. The workbook
could become the master and just overwirte the text file each time.
