I'm playing with this file functions at the moment
too. Just noticed that you don't close your files after opening them for
reading. Maybe this is the source of your freezing problem, too many files
open. I'm totally new to these functions, but maybe this is somewhere to
start looking

Subject: [amibroker] Write and read data
to files
I have my eod and intraday data in separate databases (actually separate
installations) and wanted to have some explore results from the eod available
for the intraday to provide alert signals. Previously I would copy the oed
results to excel, then compile the results into lines and paste to the alert
file as long lines of data. I hoped to stop needing all the copy/pasting and
make life easier for myself.
I have managed to do this but it does sometimes
freeze up during the intraday auto scan. I think this has something to do with
the reading of the data files and maybe filling up the memory cache, but am
not sure what the problem is or how to get around it. The formula for storing
the data into files and reading the data are below. For simplicity sake I have
changed the data to simple HHV and LLV as the actual results are from an
included file that is about 300 lines long.
The stored data is in individual files of 2 per
stock. Rxxx.txt for reslevel and Sxxx.txt for suplevel. (xxx = ticker
name) I tried to make all in one file but could not
get it to work.If someone can give me help with
the freezing problem and how to have all the information in a single file it
would be appreciated.
