soit ch une variable donnée de type chaine de caractère. on vous demande de supprimer la sous_ chaine comprise entre parenthèses de la chaine de caractères ch.

Bonsoir,
si cela peut vous aider:
CONST Faux = (0 = 1)
CONST Vrai = NOT (Faux)
DIM a AS STRING, b AS STRING, x AS INTEGER, c AS STRING
a = "ceci (est) u(n (ess)ai bi(en (di)t) coucou)"
c = a
x = Vrai
DO WHILE x
    PRINT c  
   x = SupprPar%(c, b)   
   c = b  
LOOP
END

FUNCTION SupprPar% (w AS STRING, w1 AS STRING)
DIM i AS INTEGER, j AS INTEGER, x2 AS INTEGER, ok AS INTEGER
ok = Faux
w1 = w
x2 = 0
FOR i = 1 TO LEN(w)
   IF MID$(w, i, 1) = ")" THEN
       x2 = i
       FOR j = x2 - 1 TO 1 STEP -1
            IF MID$(w, j, 1) = "(" THEN
                w1 = ""
                x1 = j
                ok = Vrai
                FOR k = 1 TO LEN(w)
                    IF NOT (x1 <= k AND k <= x2) THEN
                        w1 = w1 + MID$(w, k, 1)
                    END IF
                NEXT k
                EXIT FOR
            END IF
        NEXT j
    END IF
    IF ok THEN EXIT FOR
NEXT i
SupprPar% = ok
END FUNCTION
