It would be better to have a check before getting the string    newstring   substr  dynamicstring  -7     if characters are greater then 7 return last 7 characters else return the provided string   or do this if you need to return message or error if length is less then 7   newstring    strlen  dynamicstring  gt 7  substr  dynamicstring  -7   message     substr documentation
