@@ -361,6 +361,21 @@ Returns the keys of `dict` as an array.
 
 Sorts an array in ascending order. Returns a new sorted array. All elements must be the same type — integers, fractions, or strings. Integers and fractions sort numerically; strings sort lexicographically.
 
+### ADDE
+`ADDE(array, value)`
+
+Returns a new array with `value` appended at the end. The original array is unchanged.
+
+### TOLLE
+`TOLLE(array, idx)`
+
+Returns a new array with the element at 1-based position `idx` removed. The index must be an integer in the range `[I, LONGITVDO(array)]`; out-of-range indices raise an error.
+
+### INSERE
+`INSERE(array, idx, value)`
+
+Returns a new array with `value` inserted at 1-based position `idx`, shifting later elements one position to the right. The index must be an integer in the range `[I, LONGITVDO(array) + I]`; passing `LONGITVDO(array) + I` is equivalent to `ADDE`.

 ### SENATVS
 `SENATVS(bool, ...)` or `SENATVS([bool])`
