In french: GOTO

The GOTO statement is used to run a code identified by a label.

Important The label must be defined in the same process as the GOTO INSTRUCTION.

}

Example

Res = fOpen(NomFichier, foWrite)
IF Res = -1 THEN GOTO ERROUVRE
Res = fWrite(Res, "Traitement OK")
IF Res = -1 THEN GOTO ERRECRIT
...
RETURN True
ERROUVRE : 
Info("Le fichier " + NomFichier + " ne peut être ouvert. Vérifiez son existence.")
RETURN False
ERRECRIT : 
Info("Il est impossible d'écrire dans le fichier " + NomFichier)
RETURN False

Syntax

GOTO <Label name>
...
<Label name>:
<Label code>

<GOTO>:

Runs the code identified by the label.

<Label name>:

Name of label whose code must be run. This name must be followed by ":". This label and the GOTO statement must be found in the same process.

<Label code>:

Code that must be run when GOTO calls the label.

Remarks

Label code

Once the code of the label has been run, the program runs the lines of code that directly follow the label.

Limits of labels

Several labels with the same name cannot be used in the same process (or procedure).
A warning is displayed during the compilation of the project if a label is used by no GOTO statement.
