in Office VB code:
what does the operator ":=" mean?

example:
Worksheets("Daily Targets").Range("A5:N5").Copy _
Destination:=Worksheets("Daily Targets").Range("A" & CStr(rowCounter))

i wrote this code but i copied the it from the HELP, & then i changed the
names & variables. BUT, i'd like to understand what does the operator := is
filling for, is it an object assigning or what ... i'm not sure ??!!!
