Element Numbers - Cisco 11503 - CSS Content Services Switch Administration Manual

Chapter 8 Using the CSS Scripting Language
Using Arrays
However, if you want to print out each day separately, you must refer to a single
element within the array. For example, enter:
echo "The first day of the week is ${WeekDays}[1]."
echo "The last day of the week is ${WeekDays}[7]."
The output is:
The first day of the week is Sun.
The last day of the week is Sat.
Notice that you reference the array elements by putting the element number within
brackets ([ and ]) to tell the CLI which element you want to use. You append the
brackets to the end of the variable name (including variable indicator and braces).
Note The CSS Scripting Language numbers elements starting at 1, not at 0. Some
scripting/programming languages "zero index" their arrays; this scripting system
does not.
If you reference an element beyond the boundary of the array, you receive a syntax
error. For example, enter:
echo "The last day of the week is ${WeekDays}[8]"
%% Error variable syntax
This occurs because there is not an eighth element in the WeekDays array.

Element Numbers

To find out how many elements are in an array, pass the pound symbol (#) rather
then an element value. For example, if you want to know how many days are in a
week, enter:
set WeekDays "Sun Mon Tues Wed Thurs Fri Sat"
echo "There are ${WeekDays}[#] days in a week."
The output is:
There are 7 days in a week.
