+ forEach(array, string)
+ Compiles 'string' into a function and iterates over the 'array',
+ running the function once for each element. The function has
+ access to the special variables 'index' and 'item' which are,
+ respectively, the array index and the array element. The 'this'
+ object is set to the array element each time the function runs.
+ params: Array array (array to iterate over)
+ String string (the function source)
+ return: void
Get the next record from the input set. This will prevent jsawk
from iterating over that record.
