What is wrong with this line of code?

Question

I've been trying to start a Minecraft server. I read a small guide and followed the steps, until I tried to run this code:

java -Xmx1G -Xms200M -jar minecraft_server.exe nogui
pause

I keep getting the Windows script reader error code "800A0401", accompanied with the message "Expected end of statement". What does this mean and how do I fix it?

Does nogui need a hyphen? I'm no expert on servers but seeing as it's an argument passed to the server, it probably does. — AMJ, May 02 '20 at 21:51
@Wildingmango24 The Minecraft server is distributed as a JAR, not an EXE. What are you trying to run? — Schism, May 03 '20 at 21:11
The guide I used was the top voted comment on this other post:https://gaming.stackexchange.com/questions/226079/how-to-change-a-singleplayer-world-into-a-multiplayer-world?answertab=votes#tab-top — Wildingmango24, May 04 '20 at 03:53

The guide you linked is wrong in two ways.

It suggests, that the server is distributed in an exe file format, while it is usually a file named server.jar
It saves the start script with the vbs extension instead of bat.

The correct way

Obtain the server executable from the official site.
Note: This guide assumes, that the downloaded file is called server.jar. If not, you should rename it.
Type the following text into a notepad, and save it as start.bat in the same folder as your server executable jar-file.
Note: You can change the amount of memory allocated to your server by changing the values after Xmx and Xms. Xmx sets the maximum amount of used RAM, Xms sets the amount of RAM allocated on start. It is recommended for the two to have the same value, but it isn't required. Append M to the value to indicate megabytes, or G to indicate gigabytes.

java -Xmx1024M -Xms1024M -jar server.jar nogui
pause

(After this you can follow the original guide.)
Run the start.bat file, and you'll get an eula.txt file. Open it, and change the last false to true. Save and run the file again.
Now the server files should've generated, and the basic setup should be done. You might want to change some settings in the server.properties file.

The command should look like this:

java -Xmx1024M -Xms1024M -jar minecraft_server.1.15.2.jar nogui
pause

Yours didn't look like this, specifically this part:

-Xmx1024M -Xms1024M

There are a few other possible reasons why this didn't work. One obvious one is that you didn't install Java. Another one would be that you might have not set the EULA to 'true'. The last one I can think of is you don't have the .JAR extension showing up. If it doesn't, in File Explorer, at the top tabs, click on View. Then, check "File name extensions". If you don't understand, see the image below:

that's wrong @nishantc1527 – sportzpikachu May 03 '20 at 10:34
Even if not: why would it be right? We expect answers here to explain why something is like it is. – Joachim May 03 '20 at 10:50
I know it's correct because I launched my own server with this. But anyways, I will add an explanation. – nishantc1527 May 03 '20 at 19:40

-Xmx and -Xms mean how much RAM the server can use (Xmx), and how much will get allocated on start (Xms) You can set them to any value – Andruida May 12 '20 at 16:44
