Hello,
I'm trying to create a simple editing template for myself, just some
code that I can use for future editing needs, where I open a file,
change stuff, and then save the file. I created this simple little
script, but, it doesn't work when I run it. It complains about line 3. I
get an exception with "wrong number of arguments (0 for 1)." But, when I
do this script, line for line, in IRB, I have no problems.
Dir.chdir("C:/documents and settings/pb4072/my documents/scripts/ruby")
contents = File.read{"test1.txt"}
#The file is just a bunch of repeated "The quick brown fox..." phrases.
You need to pass File.read a simple method argument, which goes inside
parentheses, you don't need a block.

I don't understand. My line says this:
contents = File.read{"test1.txt"}
I'm using parentheses, no block. I've done this in a number of other
scripts, and, they work fine.

Those aren't parentheses, they're braces, which means you're passing a block
to it.
You have to use ( instead of { .
contents= File.read("test1.txt")
