Edit the CSV

 
Hello,

I wonder if it's possible to edit a cell in a csv file.
At first I insert values​​:

Type | Execution
BUY | 0

Then when the order is executed, I would replace the 0 with 1.

Thank you in advance!
 
I suppose you could open the file for read and write (FILE_READ | FILE_WRITE) then use FileSeek but that is very nasty and not recommended to overwrite fields like that.
