What's really amazing is how much faster my mouth works
than my brain. :-(
On re-reading the tip, I find I am really, REALLY
impressed with C style formatting. I've got to start
brushing up on that language....
Cheers,
David
P.S. Let's just say REGEX is on my list.

The tip reads:
IDL> PRINT,'I','like','Interactive','Data','Language', $
FORMAT='(%"%s %s\t%1s",a1,a1)'
Which results in the following output:
I like IDL
IDL is getting like Microsoft, doing all the thinking
for you. How did it know I wanted to abbreviate "Interactive
Data Language" to IDL!? Amazing. :-)

Thanks, but I got the answer now - I am using an old version of IDL,
which does not support c-style format :-(

Hi Michael,
testing your code I got:
% "(%"%s\n")"
% ^
% Unexpected text in format.
I am not familar with C-style format code, any suggestions ?
Thanks in advance !

You can use the format keyword of the string function to add a C-style
control character to the string. For UNIX, just add \n (newline) to the
end of your string. For Windows, add \r\n (carriage return and newline).
; UNIX version
writeu, 1, string('Hello World', format = '(%"%s\n")')
; Windows version
writeu, 1, string('Hello World', format = '(%"%s\r\n")')

HM, I played a little and came up with some text the online help:
"The Windows-Only keywords BINARY and NOAUTOMODE are now obsolete. Input/Output
on Windows is now handled indentically to Unix, and does not require you to be
concerned about the difference between "text" and "binary" modes. These keywords
are still accepted for backwards compatibility, but are ignored."
Those keywords are ignored causing lines written with the printf command
are terminated by carriage return and line feed when Windows is the OS
and line feed only for Unix. Thus "handled indentically to Unix" is at
least hard to understand.

A work-around is to use writeu in stead of printf and use the string
procedure to format the text, i.e. to write some text and a number, the
following code works
writeu, 1, String( "Hello word, the year is", 2004), 10B
but looks ugly. Any other ideas?
