Bug or Not? Taking STRING of a string whilst making leading zeros

[Carlos295pz]

The recursive function may look like this:

Code:

EXPORT ZEROS(NZ)
BEGIN
   IFTE(NN,"0"+ZEROS(NZ-1),"")
END;

Speed may not be important for that code, but it may be better to use ITERATE instead of tail.

Code:

EXPORT ZEROS(NZ)
BEGIN
   ITERATE(X+"0",X,"0",NZ)
END;
