gnIdSession is int
gnIdSession = mlInitialize()

IF gnIdSession = -1 THEN
Error(ErrorInfo(errFullDetails))
END

// Code du bouton BTN_ListeVariable
sListeVar is string = mlListVariable(gnIdSession)

SAI_Résultat = sListeVar

gnIdSession is int
gnIdSession = mlInitialize()

IF gnIdSession = -1 THEN
Error(ErrorInfo(errFullDetails))
END

// Code du bouton BTN_Creation_Variables
tParamètre is array of 1 real = [4]
tRésultat is array of 1 by 1 real = [[123]]

IF NOT mlSetVariable(gnIdSession, "i", tParamètre) THEN
Error("Echec d'écriture de la variable")
RETURN
END

sCodeAExécuter is string = "maRac = sqrt(i)"
SAI_Résultat = mlExécute(gnIdSession, sCodeAExécuter)

tRésultat = mlGetVariable(gnIdSession, "maRac")
IF ErrorOccurred THEN
Trace("Erreur: " + ErrorInfo())
END

Trace("Racine = " + tRésultat[1,1])

Trace("Liste des variables avant suppression: " + mlListVariable(gnIdSession))

mlDeleteVariable(gnIdSession, "i")
mlDeleteVariable(gnIdSession, "maRac")

Trace("Liste des variables après suppression: " + mlListVariable(gnIdSession))
