Is there a way to easily get syntax or help on a WLanguage function?

When entering a WLanguage function in the code editor:

the name of each parameter is displayed in a tooltip for the code line currently in edit. For the parameter currently in edit, hovering the parameter name with the mouse is used to display the parameter details in a tooltip.
If several syntaxes are available, it is possible to switch from one syntax to another using Ctrl + up arrow or down arrow.
the syntax of the WLanguage function is displayed in the status bar of the editor.

In the help, the parameters enclosed between [ and ] are optional parameters.

For WLanguage functions that require names of data files, controls, windows or reports, the assisted input is used to display the list of project elements corresponding to the parameter of the function currently typed.

Examples of assisted input for HReadFirst: the <Wizard> option is used to start a code wizard. This wizard asks you questions regarding the function use and automatically generates the corresponding code.

A help page is associated with each WLanguage function and property. This help page can be directly accessed from the editor by pressing F1 on the name of requested function or property.

What are the useful shortcuts in the code editor?

To display the events of a control, method, class, procedure or report block, press F2 while on the name of the desired element.
Ctrl + F2 is used to go back to the initial process or event.
To move from one process/event to another, press F2 repeatedly. To go back to the initial process or event, press Ctrl + F2 the same number of times.
Ctrl + L deletes the current line.
Ctrl + D duplicates the current line (or the selected lines) on the line below.
Tab (tab key) and Shift + Tab are used to manage the indent for the selected lines.
Ctrl + / converts the selected lines into comments, Ctrl + Shift + / removes the comments (Caution: / key on the numeric keypad).
Ctrl + R is used to automatically re-indent the displayed code.

Creating and using a procedure

To create the procedure for calculating the amount IOT:
1. Click the window background.
2. Display the events associated with the window (F2).
3. In the code editor, on the "Code" pane in the ribbon, in the "Procedures" group, expand "New" and select "New local procedure".
4. In the window that is displayed, type the name of local procedure ("Calc_IOT") and validate ("Add" button).
5. The new procedure local to the window is automatically created and its code is displayed in the code editor.
6. Write the following WLanguage code:
  
  PROCEDURE Calc_IOT(PriceBT, VATRate)
  cyIOT is currency
  cyIOT = PriceBT * (1 + VATRate/100)
  RESULT cyIOT
  
  Let's take a look at this WLanguage code:
  - The Calc_IOT procedure expects 2 parameters: the price before tax and the VAT rate.
  - This procedure declares a currency variable. This variable is used to store the calculated price IOT.
  - This procedure calculates the price IOT and returns the calculated value.
7. Close the code window (click X at the top right corner of code editor).


	Remark	When creating a procedure, comments are automatically generated BEFORE the procedure code. These comments are mainly used to specify the content of parameters and return value. It is important to fill these comments. Indeed, they will be automatically displayed in a tooltip when typing the call to the procedure in the code editor.

Let's now call the procedure from the calculation Button control.
1. Select the "Calculate" Button control.
2. Display the events associated with the Button control (press F2, for example).
3. In the "Click" event, replace the existing code with the following code:
  
  SWITCH COMBO_VAT..DisplayedValue
  // 5.5 %
  CASE 5.5
  EDT_PriceIOT = Calc_IOT(EDT_PriceBT, 5.5)
  // 10 %
  CASE 10
  EDT_PriceIOT = Calc_IOT(EDT_PriceBT, 10)
  // 20 %
  CASE 20
  EDT_PriceIOT = Calc_IOT(EDT_PriceBT, 20)
  END
  
  This code calls the Calc_IOT procedure to calculate the amount IOT. Two parameters are passed to the procedure: the price BT and the VAT rate. The result returned by the procedure is assigned to the EDT_PriceIOT control.
4. Close the code window (click X at the top right corner of code editor).

Let's now run the window test:
1. Run the window test ( among the quick access buttons). Give a price BT. Select the different values in the Combo Box control and click "Calculate".
2. The amount IOT is displayed.
3. Close the test window.

Mandatory or optional parameters?

The parameters received in the procedure can be mandatory or optional parameters. A mandatory parameter must be filled during the call to the procedure while an optional parameter can be omitted: in this case, it will take the default value defined when declaring the procedure parameters.


	Remark	When declaring a procedure, the optional parameters are the last parameters (they are always specified after all mandatory parameters).

In the following example, the Multiplication procedure uses an optional parameter, Nb2. This optional parameter is indicated after the mandatory parameters, by specifying its default value. In this example, the default value of optional parameter is set to 10.

PROCEDURE Multiplication(Nb1 is int, Nb2 is int=10)

MyResult is int

MyResult = Nb1 * Nb2

RESULT MyResult

The code used to call the procedure is as follows:

res is int

res = Multiplication(6)

// Res is equal to 60

========================

The WLanguage code of the procedure is:

PROCEDURE Test_Reference(P1)
P1 = P1 * 2
The WLanguage code used to call the procedure is:

T is int
T = 12 // T is equal to 12 before the call
Test_Reference(T)
// T is equal to 24 after the call
Example:
- The WLanguage code of the procedure is:
  
  PROCEDURE Test_value(LOCAL P1)
  // Local indicates that the parameter will be passed by value
  P1 = P1 * 2
- The WLanguage code used to call the procedure is:
  
  T is int
  T = 12 // T is equal to 12
  Test_value(T)
  // T does not change
