R: [Tutor] os.spawnv OSError errno 2 No such file or directory

[Isaac]

Hey, Marcel, thank you for the suggestion.

It's definitely a good one, but alas, I've tried giving an absolute pathname
several times, in several ways, including using "c:\\bat\\ls.bat",
"c:\\command.com," and putting the batch file in other directories, including
the root of the drive and also the python directories.  Always getting the
same result.

I'm wondering if it's not a weirdness of win95/98 as opposed to NT, but since
the os.system() call works, I would think spawnv should, too.

I've even tried using spawnve and including os.environment in the hopes that
would help it process the path, but no luck.

Time constraints have forced me to begin a workaround using os.system(), but
it's far from ideal.

Thanks again!

Best,
Isaac
