[...] We will then be able to perform operations on these data, comparisons, find them later, manipulate them, etc. We are going to create a NEW WINDOW and type a little bit of CODE, to see how the VARIABLES are declared, and how they are used We create a WINDOW : We click on the NEW button In NEW, we click on WINDOW We click on WINDOW again We click on BLANK Then we click on OK We are going to call this window VARIABLE Then on RECORD One positions oneself on the title bar of the WINDOW And one clicks with the RIGHT MOUSE BUTTON One types VARIABLE Then one clicks on APPLY And finally on OK The window has the title: VARIABLE One resizes the WINDOW One will add a BUTTON in the WINDOW One clicks on BUTTON One drags and positions the BUTTON in the window And one releases the BUTTON The BUTTON gets stuck in CREATION One right-clicks on the BUTTON One clicks on the CODE option We are going to DECLARE A VARIABLE A variable declaration is done by typing the NAME I want to give to the variable, followed by 'IS or 'IS AN' And the TYPE OF THE VARIABLE We are going to suppose that I want to manipulate a PRICE I will declare a VARIABLE that I will call PRICE We will then type: IT IS A FINANCIAL EXPERT (FINANCIAL EXPERT being a type of variable) And we choose FINANCIAL EXPERT from the list The VARIABLE is green in color (Price) It is currently declared but not used Before Price, we notice that MO has been added by the program, to make MOPRIX (mo as monetary) I will enter in the line below: Price = 15.26 I assign a VALUE to my variable (15.26) - I have a MEMORY ZONE called Price that I declared of type MONETARY This indicates to WINDEV that I will store money: a value representing money The value I give it is 15.26 There are many types of VARIABLES: On the line below, we type: mavariable is a N.B. : BOOLEEN corresponds to TRUE or FALSE: 1 or 0 One can declare a string of characters: mavariable is a One types string Below Mavariable is a string, One types : Mavariable = On tape (double-guillemets for any string of characters) The GUILLEMETS are the delimiters of the string of characters Inside the GUILLEMETS, one types: Hello, do you find this course interesting?
