Re: Cann't create a file

Thank you all for your input. I tried both variations using "or" instead of || and () when using ||. Both caused my server to reboot. Go figure. Back to the drawing board.

Chris.

First, use the open( ... ) form of the function.. given the issues with operator precedence it would be very wise to use the parenthesis (also known as brackets). Second, if your server is rebooting I highly recommend pulling out the debugger. `perl -d`<script>. Then single step through each line until you hit the one that makes your server reboot. If you're using CGI through Apache and don't have the option of running a debugger, then one approach you might take to finding the line causing the issue is sprinking sleeps and debugging statements.. e.g. `$\| = 1; # turn on autoflushing of print statements print( "<p>About to open file..</p>" ); sleep( 5 ); open( ... ) or die( ... ); print( "<p>About to append to file..</p>" ); sleep( 5 ); print FILEHANDLE $statement; ...` [download] and soforth..

  $| = 1; # turn on autoflushing of print statements
  print( "<p>About to open file..</p>" );
  sleep( 5 );
  open( ... ) or die( ... );
  
  print( "<p>About to append to file..</p>" );
  sleep( 5 );
  print FILEHANDLE $statement;
