How to load variables from file into windows environment variables in Jenkins pipeline?

I have the following Jenkinsfile

node  {
    stage 'checkout'
    deleteDir()
    checkout scm

    load 'LoadTheseVariables.txt'  

    echo "MYKEY: ${MYKEY}"
    echo "REPO: ${REPO}"

    bat 'echo MYKEY is %MYKEY%'
    bat 'echo REPO is %REPO%'        
}

The file LoadTheseVariables.txt contains:

MYKEY="ThisIsTheKey"
REPO="ThisIsTheRepo"

The output of the Jenkins build is:

<..snip..>
[Pipeline] load
[Pipeline] { (LoadTheseVariables.txt)
[Pipeline] }
[Pipeline] // load
[Pipeline] echo
MYKEY: ThisIsTheKey
[Pipeline] echo
REPO: ThisIsTheRepo
[Pipeline] bat
[test] Running batch script

D:\Jenkins\workspace\test>echo MYKEY is  
MYKEY is 
[Pipeline] bat
[test] Running batch script

D:\Jenkins\workspace\test>echo REPO is  
REPO is 
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

The Jenkins pipeline can see the variables but why can't my windows cmd environment see the variables? I even tried this step before the bat commands at the end: bat 'refreshenv' but that didn't reload the environment with those variables.

How can I load variables from a file in a Windows job and have them loaded into the environment at run time?

The solution is to use double quotes instead of single around the bat command. Seems to work fine.
