Retrieving items from an Icon table

Tech Computer Center logo

Once you have stored a value v into a table t using key k, you can retrieve the stored value using this expression:

For example, if the variable ``today'' contains the three-letter string for the day of the week, and you have a table ``dayNumbers'' set up as shown in the previous page (see `Storing items in an Icon table'), the expression
will return the value stored under that key. If ``today'' is the string "Tue", the expression ``dayNumbers[today]'' will produce the integer 3.
