Subject: RE: Park and others!.....Possible memory bug in Ruby? I'm stumped	!

All-

Thanks a million, everyone, for your comments in this thread.

One follow up:

Recall that in the code I asked about (included in thread below), one of the errors occured at line 15, where I write stuff to a new file. This line reads:

   File.new("./output/"+field[0],"w+").write(content2)

Because an error occured here in one test, it appears that this line, like those before it, may also create an OS file. If this is true, is there way to rewrite THIS line to force a close the file during or just after the line executes? Or, perhaps immediate garbage collection occurs with this
command, so I needn't worry.

Thanks again!

-Kurt Euler

correctly inserts the contents of file "intro_subtemplate.txt" into a
template file during each iteration, resulting in the creation of some 189
identical but differently named files in directory "./output". (There are

These error messages caused by too many open files.

Following three lines should be placed before IO.foeach loop.

inserta = File.new("./input/intro_subtemplate.txt").read
insertb = File.new("./input/install_unix_subtemplate.txt").read
insertc = File.new("./input/files_changed_sp_num-1_subtemplate.txt").read

Or

inserta = File.new("./input/intro_subtemplate.txt").read

should be

f = File.new("./input/intro_subtemplate.txt")
inserta = f.read
f.close
