- Good enough. Now--how about echoing an *empty* line? Use the command
- echo. > result

- of the file. Is that space character important? You bet. Try
- echo. | date
- (which ought to allow you to display the date without getting prompted
- for a new date) to see why.
No whitespace is needed around redirection or pipe symbols. Just use
'echo.> result' and 'echo.| date' to do what you want.
You can also use the whitespace before redirection to your advantage.
I like a space between my prompt and the cursor. I originally used
ansi.sys to get it, but naturally got strange results when running on
machines with different console drivers. I wanted a portable solution
and found that 'prompt $p$g > nul' would always work.
