GOTO statement

In french: GOTO

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

Important: The label and the GOTO statement must necessarily be defined in the same process.

Example

Res = fOpen(FileName, foWrite)
IF Res = -1 THEN GOTO ERROPEN
Res = fWrite(Res, "Process OK")
IF Res = -1 THEN GOTO ERRWRITE
...
RESULT True
ERROPEN:
Info("The file " + FileName + " cannot be opened. Check its existence.")
RESULT False
ERRWRITE:
Info("Unable to write into " + FileName)
RESULT 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 code lines 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.
