As a former webmaster I'm of course used to idiot-proofing anything released into the wild so it is usable by everyone on every machine ;') The script to change directories for PyScripter is a PyScripter startup file, not a bat file. I meant I needed an additional bat file that would do the same for MS-DOS.
You're not running MS-DOS. You're running a DOS BOX under Windows, which is a cmd shell.
As usual I was marvelously unclear. But anyway, I
figured it out. Here is the batch for starting 2.7 and ensuring its in the
2.7 working directory. Since I'm running 2.7 and 3.3 I just want to make
sure I don't trip over my own feet. I know I could do all this with
virtualenv, but I'd rather a simple hack than all that mess. The two Pys
are now separated in every possible way:
MS batch file py27.bat
python2.7 -i -c "import os;os.chdir('c:/python27/jimprogs');del(os)
That seems rather silly. Why not ------py27.bat------- c: cd \python27\jimprogs python2.7 %$ ---------------------I probably don't have the right syntax for %$, but there is a pseudo-variable you can use which means "all the parameters that were on the batch file invocation. This is the generalization of %1 %2 %3 %4
There's also a pair of cmd.exe internal commands, with names something like SETLOCAL and ENDLOCAL that let you save and restore the current state of the environment including drive letter and current directory.
------py27.bat------- SETLOCAL c: cd \python27\jimprogs python2.7 %$ ENDLOCAL ---------------------Or you could use PUSHD and POPD if the only thing you're customizing is the directory.
