StringReplacePart

StringReplacePart["string", "snew", m, n] replaces the characters at positions m through n in "string" by "snew".

StringReplacePart["string", "snew", , , , , ... ] inserts copies of "snew" at several positions.

StringReplacePart["string", "", "", ... , , , , , ... ] replaces characters at positions through in "string" by "".

StringReplacePart uses position specifications in the form returned by StringPosition.

When a list of "" is given, its length must be the same as the length of the list of positions.

When multiple positions are given, all refer to the original "string", before any replacements have been done.

StringReplacePart[s, "", ... ] can be used to delete substrings.
