Ruby Equivalent Syntax

I see a below syntax in one of the ruby files written by an user. Can someone help me in understanding what the below code means?

if fieldWidth==nil
  fW = regStr.length
else
  fW = fieldWidth
  regStr.rjust(fW,'0')   # Left pad with 0s if fW > regStr.length
end

if fW >= fWOld: fWMax = fW end
fWOld = fW
regStrIx = 0

In the context of the if conditional, a footnote in The Ruby Programming Language on page 119 : "Ruby 1.8 also allows a colon, but this syntax is no longer legal in 1.9." A newline or semicolon or the keyword then is correct.
