Having just read columns 1 through 5 to get a value for TYPE, SAS is now positioned to look for the next variable starting at column 6. The "+2" tells SAS to move two columns to the right, so it will start looking for a value for COLOR at column 8.

It means that there are 2 ignored characters to the right of position 5 (the end of variable Type) before variable color is read.
What is the impact on the output? Some things are left for the user to figure out. A simple way to figure out what the impact on the output will be is to actually run the code.
