如何用simtalk语言实现固定存储中的装卸载功能，我只知道混合存储的，怎样在上面修改

(sensorID : integer)
is
i, j, k, m, p, w:integer;
Name:string;
Obj,Res:object;
do
p:=ascii(ProductType)-64;
w:=WH_var[3,p].YDim;
if CurrTask=1 then
for k:=1 to w loop -- 先搜索存储区块
-- 再按行搜索,即按储位搜索
for i:=WH_var[3,p][3,k] to WH_var[3,p][4,k] loop
-- 然后按货架搜索
for j:=WH_var[3,p][1,k] to WH_var[3,p][2,k] loop
-- 最后按货架层搜索
for m:=1 to WH_nums loop
Res:=str_to_obj(sprint("Store_",m));
Obj:=str_to_obj(sprint("Status.StoreData_",m));
if Res[j,i].empty=true then
Obj[j,i]:=sprint(ProductType, PartType);
@.cont.move(Res[j,i]);
@.backwards:=true;
return;
end;
next;
next;
next;
next;
promptmessage(sprint(ProductType,"类物品存储空间已满，请先释放相应空间！"));
@.cont.move(Drain);
@.backwards:=true;
else
