Hi John,

I has a similar problem just last week.
This is the script I came up with and it worked fine for me.
I'm not taking any credit - the 'try - on error - end try' code came from Matt Neuburg's book (pp 344 and 345) together with gems from others on this list!
----------
global this_file
-- Create / open the file
set path_name to (path to desktop) as string
set file_name to path_name & "MyChangeLog.log"
try
set this_file to open for access file file_name with write permission
on error
close access file file_name
display dialog ("Problem opening log file")
return
end try
-- Clear any existing data and write the start time
try
set eof this_file to 0 -- Erase file if it exists
write_line("Starting at " & (current date) & return)
on error
close access file file_name
display dialog ("Error writing to file log (1)")
end try
-- Do your stuff here, probably in a loop
-- Create your log message
set this_name to "MyFile.jpg"
set log_message to "Done stuff with " & this_name & return
set log_message to log_message & "Updated: " & "MyOtherFile.jpg" & return & "---------" & return
-- Append the log message to the file
try
write_line(log_message)
on error
close access file file_name
display dialog ("Error writing to file log (2)")
end try
-- End of your stuff loop
-- Write the end time and close the file
try
write_line("Ending at " & (current date))
close access file file_name
on error
close access file file_name
display dialog ("Error writing to file log (2)")
end try
-- This sub-routine simply writes a string to the file with a return appended
on write_line(the_string)
write the_string & return as string to this_file
end write_line
----------------
Hope it helps,
Andrew
