How to pause a batch while executing? - timeout /t 60

Secnario: 

I need to copy a .dll assembly to a couple of places and register it in in the Global Assembly Cache.

A .bat file was provided as below:

=====================

@echo off
copy "C:\TK463\Chapter19\Lesson3\Starter\TK463 Chapter 19\TK463.CalculateCheckSum\bin\Release\TK463.CalculateCheckSum.dll" "%ProgramFiles(x86)%\Microsoft SQL Server\110\DTS\PipelineComponents" /Y
copy "C:\TK463\Chapter19\Lesson3\Starter\TK463 Chapter 19\TK463.CalculateCheckSum\bin\Release\TK463.CalculateCheckSum.dll" "%ProgramFiles%\Microsoft SQL Server\110\DTS\PipelineComponents" /Y
echo.
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\x64\gacutil" /u TK463.CalculateCheckSum
echo.
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\x64\gacutil" /i "d:\ProgramFiles%\Microsoft SQL Server\110\DTS\PipelineComponents\TK463.CalculateCheckSum.dll"
echo.
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\x64\gacutil" /i "d:\ProgramFiles(x86)%\Microsoft SQL Server\110\DTS\PipelineComponents\TK463.CalculateCheckSum.dll"
=====================

Solution:

In order to make it work, I need to make the following changes:

1. Change C:\TK463\... to C:\Users\CK\Downloads\...

2. Change "%ProgramFiles(x86)%\Microsoft SQL Server\110\DTS\PipelineComponents" to "D:\Program Files(x86)\Microsoft SQL Server\110\DTS\PipelineComponents", which is the DTS folder on my pc, note there is space between Program and Files(x86), similarly

3.  Change "%ProgramFiles%\Microsoft SQL Server\110\DTS\PipelineComponents" to "D:\Program Files\Microsoft SQL Server\110\DTS\PipelineComponents"

4. I added timeout /t 60 at the end of the batch file to pause the message for 60 seconds.
