<strong>zl</strong>:greaterp<br />

(graphic-char-p #\A) => T<br />

(graphic-char-p #\c-A) => NIL<br />

(graphic-char-p #\Space) => T<br />

<strong>zl</strong>:greaterp number &rest more-numbers Function<br />

<strong>zl</strong>:greaterp compares its arguments from left to right. If any argument is<br />

not greater than the next, <strong>zl</strong>:greaterp returns nil. But if the arguments<br />

are monotonically strictly decreasing, the result is t. Examples:<br />

(<strong>zl</strong> :greaterp 4 3) => t<br />

(<strong>zl</strong>:greaterp 4 3 2 19) => t<br />

(<strong>zl</strong>:greaterp 4 3 1 2 9) => nil<br />

The following function is a synonym of <strong>zl</strong>:greaterp:<br />

<strong>zl</strong>:haipart x n Function<br />

Returns the high n bits of the binary representation of lxi, or the low -n<br />

bits if n is negative. x must be an integer; its sign is ignored. <strong>zl</strong>:haipart<br />

could have been defined by:<br />

(defun <strong>zl</strong> :haipart (x n)<br />

(setq x (abs x))<br />

(if (minusp n)<br />

(logand x (1- (ash 1 (- n))))<br />

(ash x (min (- n (<strong>zl</strong> :hau1ong x)) 9))))<br />

:handle-condition cond ignore Message<br />

:handle-condition is an interactive handler message to instances of<br />

dbg: basic-handler.<br />

cond is a condition object. You should handle this condition, ignoring the<br />

second argument. :handle-condition can return values or throw in the<br />

same way that condition-bind handlers can.<br />

:handle-condition-p cond Message •<br />

:handle-condition-p is an interactive handler message to instances of<br />

dbg:basic-handler. This message examines cond which is a condition object.<br />

It returns nil it if declines to handle the condition and something<br />

other than nil when it is prepared to handle the condition.
