# 1 Re: Please Help -- Data logger on text (.txt) file
First the general formula for writing in a file is :
open file for output as #1 'open the "file" for outputing in it
print #1, txtlog 'writing in it the txtlog container
close #1 'closing the file -important-
each calling for it will print in a new line the txtlog , for checking the size of the file, you may use the function "filelen()" and make an "if" check after each "print" and to know if it must change the "file" or nop .

i use this code but a problem is that this code are deleting previous logs
for example:
when i write [Hello] in text box and hit the bottun it saves in log.txt
but for second time when i write [How Are U] in text box and hit the bottun
[How Are U] replaced with [Hello]
but i want a code that every time i enter a diffrent things in text box
it make a new line under previous records and add new text
and when the log reaches to for example 50kb it automaticlly make new
.txt file (example: old log = log.txt new generated log = log1.txt )
and automaticlly fix the log file path to new log.

open file for append as #1
about the new log, as told u before, use the filelen() function to check if the file size is 50 or not yet, for example
if filelen(file) = 51200 then Write_In_New_File() else Write_In(file) ...

yea I told you, open it for appending data like this :
"open file for append as #1"
instead of this:
"open file for output as #1"
