I have a batch file that spawns a shell with a modified path with the following command:
cmd /K set PATH=%PATH%;<additional path locations>
I want to set additional environment variables for the spawned shell as well. Is there any way to do that?

Simply add another variable on a new line using set as shown in your example. You will also want to remove the /K switch from the first line as execution will stop after that line.
set NEWVAR=SOMETHING
will create a new variable called NEWVAR with the value SOMETHING. If you wish to keep the same behavior and keep cmd open with the /K switch just put it at the end.
example:
set PATH=%PATH%;C:\Folder;
set NEWVAR=SOMETHING
echo %NEWVAR%

You could also combine them into a single line as follows:
set A=foo & B=bar & C=baz
This way, you could avoid having to modify the original script and run it like so:
set A=foo & B=bar & C=baz & c:\path\to\foo.bat

1When running this from an npm/yarn script, I had to prefix each variable assignment with set. e.g. set A=foo & set B=bar & set C=baz & c:\path\... – Greg K – 2019-01-16T18:02:00.957
1Thanks - that worked like I wanted it to. I put cmd /K at the end because I wanted to use the shell after it had finished executing my commands. – quanticle – 2009-08-15T01:10:22.353
2You can also write a batch that makes all necessary changes to the environment and then simply start your
cmdinstance withcmd /k setvars.cmd. This is for example how Visual Studio sets up its command prompt. – Joey – 2009-08-15T12:26:13.707
