[SOLVED] How can I assign the output of a function to a variable using bash?

Issue

I have a bash function that produces some output:

function scan {
  echo "output"
}

How can I assign this output to a variable?

ie. VAR=scan (of course this doesn't work - it makes VAR equal the string "scan")

Solution

VAR=$(scan)

Exactly the same way as for programs.
