>>-BITAND--(--string1--+----------------------------+--)-------><
'-,--+---------+--+--------+-'
'-string2-' '-,--pad-'
returns
a string composed of the two input strings logically ANDed together,
bit by bit. (The encodings of the strings are used in the logical
operation.) The length of the result is the length of the longer of
the two strings. If no
pad character is provided, the AND
operation stops when the shorter of the two strings is exhausted,
and the unprocessed portion of the longer string is appended to the
partial result. If
pad is provided, it extends the shorter
of the two strings on the right before carrying out the logical operation.
The default for
string2 is the zero length (null) string.
