Editor (GUI?)
- editor: creat text file and doesn’t change the original script
- save and press run button to run the "editor file" on matlab(have to select the currect folder at current folder on the left side)
- "clear" cleans all the above command
- don't always relay on the gui, can easily change the value by issuing new command Eg. b= 111 Or right click on the work space.

Command History - Shows a record of command issued

Problem
Setting key word as variable will overwrite the actual command Eg. Clear = 10, this will make the previous clear command unusable
Cannot start a variable with a number
