WRITELN, or you can use the result of a function in another computation or test. This tutorial shows how to call parts of the string and manipulate the data. Though it is not advised to use goto statement in your program. A typical run of this program is shown below. The complete program is shown in Figure. The rest of the program involves nested selections whose details will be covered soon. We give below an example run of this program.
