en cours. Pour rappeler la valeur dans la mémoire en cours, pressez [ MRC ]. Pour clarifier la mémoire en cours, pressez deux fois [ MRC ]. Voir l’Exemple 4.

zLa calculatrice possède dix variables de mémoire pour une utilisation répétée: A, B, C, X, Y, M, X1, X2, PROG1 et PROG2. Vous pouvez stocker un nombre réel dans les variables A, B, C, X, Y, M, X1, X2 et deux expressions dans PROG1 et PROG2. Voir l’Exemple 5.

*[ P/V RCL ] rappelle toutes les variables.

*[ SAVE ] vous permet de sauvegarder les valeurs des variables.

*[ 2nd ] [ RECALL ] rappelle la valeur de variable.

*[ 2nd ] [ CL-VAR ] calrifie toutes les variables, sauf PROG1, PROG2.

*[ 2nd ] [ CL-PROG ] calrifie le contenu de PROG1, PROG2.

(Note) : En plus de presser la touche [ SAVE ] pour stocker une valeur, vous pouvez également assigner des valeurs sur la variable de mémoire M par [ M+ ] ou [ 2nd ] [ M– ]. Cependant, toute valeur actuellement stockée dans la variable M sera effacée et changée avec la nouvelle valeur assignée.
