Entering a New Expression into the Data View
Because variables are actually expressions— in fact, lvalues that evaluate to a memory location— you can enter an expression into the Name field to troubleshoot data problems.
To add a new expression, double-click on Add New Expression in the Data View and begin typing.
Some examples:
*View just a sub-element of a structure, by entering it as a new expression:
A new expression is added. This is the same as diving on the sub-element.
*Increment a variable:
*Add or subtract variables, assuming some relationship:
*Add a global variable. Type the variable name into the Name column and TotalView automatically enters the type and value.
The value updates in the Data View as you run through your program.
