value in a series and returns the series after the change." I would say
"Changes a value in a series and returns the part of the series after the
change."
Um, the docs are accurate here. Watch:
>> s: "1234567890"
== "1234567890"
>> r: change s "def"
== "4567890"
>> print head r
def4567890
>> s
== "def4567890"
Note that 's and 'r are the same string.
> Moving onto to change/part, "Limits the amount to change to a given length
or position," is not entirely accurate since its return value indicates that
the whole of the range was changed. If what it does is not a bug, it would
be somewhat more accurately said "Enforces change limited to a given length
or position."

>> s: "1234567890"
== "1234567890"
>> r: change/part s "defghi" 2
== "34567890"
>> print head r
defghi34567890
>> print s
defghi34567890
Note that positions 1 and 2 in s have been replaced with the string
"defghi". A length of "2" from the start of the string.
>> s: "1234567890"
== "1234567890"
>> r: change s "defghi"
== "7890"
>> print head r
defghi7890
>> print s
defghi7890
Note that the first six characters of the string have been replaced.
