Hi all,

I’ve a list

```
{{a1, a2, ...}, {b1, b2, ...}, ...}
```

Is a handy way to multiply each list item by, say, x?

Not directly (i.e. in the way that APL, Mathematica, MATLAB and others can), but we can define a handler to make it fairly, er, handy.

```
on run
set nestedList to {{0, 1, 1.5, 2, 3}, {4, 5, 6, 7}, {{8, 9, 10}, {11, 12, 13}}, {14, {15, 16}, 17}}
multiplyNestedItems of nestedList by 2
end run
to multiplyNestedItems of aList by aNumber
if class of aList is list then
set newList to {}
repeat with listItem in aList
set end of newList to multiplyNestedItems of listItem by aNumber
end repeat
newList
else if class of aList is class of (aList as number) then
return aList * aNumber
end if
end multiplyNestedItems
```
