Getting a "Missing token: ASSIGN" error when running OpenModelica script through a batch file

I am trying to run an OpenModelica script using a DOS .bat file. But facing some issues. The batch file runmodelica.bat has

%OPENMODELICAHOME%\bin\omc testscript.mos

The file testscript.mos is

loadModel(Modelica)
getErrorString()
loadFile("HelloWorld.mo")
simulate(HelloWorld)
getErrorString()

If I run the commands in the testscript.mos file from an OM Shell by changing to that directory, everything works fine. But If I run the batch file from the DOS prompt, I get the following error

Error processing file: testscript.mos
[C:/Users/blahblah/testscript.mos:2:1-2:1:writable] Error: Missing token: ASSIGN

# Error encountered! Exiting...
# Please check the error message and the flags.

Execution failed!

The HelloWorld.mo file comes with the standard installation and I haven't modified it

class HelloWorld
  Real x(start = 1);
  parameter Real a = 1;
equation
  der(x) = - a * x;
end HelloWorld;

I am new to OpenModelica and searched online but couldn't find a solution. Any help is appreciated.

All the commands run in the OM Shell but not when invoked from the bat file.

The script code needs to be valid Modelica, so you need ; after each command.

loadModel(Modelica);
getErrorString();
loadFile("HelloWorld.mo");
simulate(HelloWorld);
getErrorString();
