6.10.2. MODIFYING AN APPLICATION

Library, data, program creation and edition

• To declare a new library, go to the library mode of the application, press the Add key in the pop-up menu, then

select the library to load and enter the corresponding identifier for the project.

• To create a new data, select the type of variable and press the New key in the pop-up menu.

• To add a frame or a point in a frame, go to it and press the New key in the pop-up menu.

• To add a tool, go to a tool and press the New key in the pop-up menu.

For further information on modifying programs, consult the Reference Manual for the VAL3 language.

Note:

It is not possible to delete a variable, a program, a point or a tool if they are used in a program. It

is not possible to add a parameter or a local variable to a program if the application is active.

Program editor

The VAL3 program editor can be accessed via the list of programs in the application manager; it enables you to

modify programs (to insert, delete, or modify an instruction).

Each instruction added to the editor is checked. If it is not valid, an error message is displayed and the instruction

is refused. In the event of an error, see the reference manual for VAL3 language to correct the instruction

concerned.

The editor proposes a program tree, which means that the instructions set up (if, while, for) are displayed in the

form of a node that can be expanded or contracted.

Example:

COLLAPSED EXPANDED

+ if nb>12 - if nb>12

- switch nb

- case 5

break

+ case 7

endSwitch

else

put("error")

endif
