You can display the Modify Variable Dialog by pressing the Modify Variable button in the Watches page of the Debugger.
The Modify Dialog shows basic information about the variable. It also displays the current value of the variable and lets you enter a new value. For example, entering a new integer value in the New Value box and clicking OK changes the variable to the new value.
Depending on the type of variable, the display will be slightly different. Reals, Integers and Strings have their own displays. Variables are generally shown in the format specified in the Watch Properties dialog.
1. Integers. If the value is an integer, you will have the option of entering either an integer or characters, since integers are sometimes used to store characters.
