I am working on an AppleScript that, in part, needs to:
1) see if file "data" exist on desktop
2) if so, look to see if there is data in the file, if not, wait a
couple seconds and try again
3) if there is data, read the first line and remove it from the data
file
4) process the data...
5) return to step 1 (or maybe 2)
I have been tinkering for a while, but can not get my prog to read one
line at a time (read paragraph 1 seems to read the whole file), nor can
I get it to delete the text that is being processed.
The data file will be getting updated from elsewhere, which is why I
need to keep checking...
If, for some reason, this is not possible, it would also be OK to read
the whole file, delete all read lines, then process it one line at a
time in a repeat loop... hmmm... that may be faster...
any ideas are appreciated.
