Wow, that's a boatload of switches. Is all that really necessary?

Also, why waste time doing the architecture check if you are going to make two separate batch files, one for 32 and one for 64? It'd be far more logical to check it then set variables as needed. Also I get why you are doing the bindir thing, but you can't guarantee that the batch file will be in the MC server folder. I know I don't want my server folder in the path, and I'd be putting this batch in the path so I wouldn't use the path to the batch as the place to go.

Also, for 32 bit processor_architecture won't be x32 it's x86. Speaking of x86, bear in mind that using processor_architecture alone isn't totally reliable. My system is 32 bit but the processor_architecture var says x86. You need to also check for processor_architew6432 which on my system correctly returns AMD64.

I'd do it like this, personally:

@echo off
setlocal
set "config=%~1"
rem ***********************************
rem CONFIGURATION:
rem
set defaultConfig=s11
set autoRestart=Y

if "%config%"=="" set config=%defaultConfig%
if /i "%config%"=="s11" (
 set serverName=Sylvcraft's 1.11.2 Server
 set serverPath=d:\games\minecraft\spigot111
 set serverJar=spigot-1.11.2.jar
 set ramInitial64=8G
 set ramMax64=12G
 set ramInitial32=512k
 set ramMax32=1G
)
if /i "%config%"=="s10" (
 set serverName=Sylvcraft 1.10.2 Server
 set serverPath=d:\games\minecraft\spigot110
 set serverJar=spigot-1.10.2.jar
 set ramInitial64=4G
 set ramMax64=4G
 set ramInitial32=512k
 set ramMax32=1G
)
if /i "%config%"=="tl" (
 set serverName=Sylvcraft TekkitLite Server

 set serverJar=tekkitlite.jar
 set ramInitial64=4G

rem

 set rM=%ramMax64%

I remarked the crazy switched version because Java was complaining about the switches on my box. Personally, I've had no problems with the more slim version I used above.
