generate values
Description
!x1 : x2, x3, ..., xn
!x1 is a generator.
If x1 is a file, !x1 generates the remaining lines of x1.
if x1 is a string, x1 generates the one-character substrings of x1, and produces variables if x1 is a variable.
If x1 is a list or record, !x1 generates the elements of x1, which are variables. The order of generation is from the beginning to the end.
If x1 is a set, !x1 generates the members of x1 in no predictable order.
If x1 is a table, !x1 generates the elements of x1 as variables in no predictable order.
Parameters
- x1
- file, string, variable, list, record, set or table
- returns
- successive values of x1 until failure.
