and (clj)
(source)macro
(and)
(and x)
(and x & next)
Evaluates exprs one at a time, from left to right. If a form
returns logical false (nil or false), and returns that value and
doesn't evaluate any of the other expressions, otherwise it returns
the value of the last expr. (and) returns true.

CCL-PROGRAM is a CCL program name (symbol)

In the latter case, the execution overhead is bigger than in the former).
No I/O commands should appear in CCL-PROGRAM.
Read buffer is set to STRING, and write buffer is allocated automatically.
It returns the contents of write buffer as a string,
and as side effect, STATUS is updated.
If the optional 5th arg UNIBYTE-P is non-nil, the returned string
is a unibyte string. By default it is a multibyte string.
