>>-DELSTR--(--string--,--n--+-----------+--)-------------------><
'-,--length-'
returns
string after deleting the substring that
begins at the
nth character and is of
length characters.
If you omit
length, or if
length is greater than
the number of characters from
n to the end of
string,
the function deletes the rest of
string (including the
nth
character). The
length must be a positive whole number or
zero. The
n must be a positive whole number. If
n is
greater than the length of
string, the function returns
string unchanged.
