What does this $ mean?

[Anonymous]

Hi,

Looking at the below SUM statement,

sum(

  {

  <

  col1={'1'},

  col2 = {'$(=max(col2))'},

  col3 = {'YTD'}>

  }

  amount

  )

when it's evaluated, looks like the end result of col2 may look something like col2 = '123'.  My question is about the $ (dollar) sign

there.  Can someone explain to me what the $ sign mean when it's used like this?
