Sequential read of a collection

Question

Hello!
I have defined a collection in this way...
TYPE TABLA_SITUACION_TRIB_ACT IS TABLE OF VARCHAR2(2) INDEX BY VARCHAR2(10);
g_SituacionesDeclaActual TABLA_SITUACION_TRIB_ACT;
When I load that collection..
How can I read this collection sequentially?
Obviously the next "solution" doesnt works... :-)
FOR i IN 1..g_tabla_situacion_trib.COUNT
LOOP
v_valor:=G_TABLA_SITUACION_TRIB(i).COD_DECE_SITR;
END LOOP;
