enumeration

The awk extraction and reporting language does not directly support enumeration. However, it is possible to simlate enumberation by using a variable and [[nudge?]] operator combination. In the following example we enumerate the values for a set of fruit names:

 BEGIN {
   n=1    # We are enumerating from a value of one
   apple=++n
   banana=++n
   cherry=++n
   # We give raspberry an explicit value of eighteen
   n=raspberry=18
 }
