How to remove New line character from batch variable

问题

Good Day All! I have a batch script, and when I echo a variable like this

echo %variable1%

I get out put like this

TestLine1
TestLine2
TestLine3
TestLine4

My goal would be to modify this variable to remove all the newline characters so the output would look more like

TestLine1TestLine2TestLine3TestLine4

Is there a simple way to do this without creating files? Thank you for your assistance.
