Hello Petr,

I am on linux so I cannot test your problem.

But maybe you can try to replace anti slash  \ by slash / in your example file path:
C:/Petr/ChucK/examples/basic/whirl.ck

ChucK is coded in C++ and in this language \ is used for special characters in strings (\n means carriage return \t means tabulation ...).

Have a nice day
Julien

Hello,
I wonder if this issue only occurs with Windows 7 or if there's someone
here who uses a different version of Windows and who has also
encountered this behavior.
I downloaded and installed the latest release of ChucK and wanted to try
out one of the example files (named whirl.ck). So I copied the
"examples" subdirectory to my preferred location, launched the command
prompt, supplied "chuck.exe" with the path and filename of the file, and
I got the following:
[chuck]: unrecognized escape sequence: \P[chuck]: malformed filename
with argument list...
-->  'C:\Petr\ChucK\examples\basic\whirl.ck:'
First of all, I did not add a colon after the filename, which this
statement seems to claim I did.
Second, I'm not sure what \P means.
Could anyone please suggest a way of fixing this?
Thanks in advance.
Petr
