Chapter 3 w Variables, constants, and calculations DIM statements - declaration temporary memory locations identifier, data type, scope data types - values string, integer, currency naming rules - conventions

Constants named - define with CONST - name, data type, and value –numbers or strings intrinsic - VB built in –vbRed - predefined declaring variables scope of variables - lifetime global - all procedures module - all procedures in form local - within procedure w Calculations - numbers only change text to number - VAL function

w Arithmetic operations order of operations, precedence * / before + - parentheses alter order w Formatting data - look formatting function values not used in calculations w Counting and Accumulating Sums module-level variable w option explicit - forced to declare variables
