I have a VI which write a certain number of data columns to a file with headers. the headers are written in a previous seq loop and then the data is added afterards. All works fine, however!
IF I want to replace this dats file, say the data is not as I expect it and I rerun the progrma the original header file is replaced but the old data now appears at the bottom of the new stuff. Its not a huge issue but I expect I can re-write a new file with new header and data columns.
The problem is having the append option for the data i.e appending it to the header, writing the new header only re-writes the header part of the file and once the new data comes along the append kicks in and appends the old data to the new.
Any suggestions.
Will.
