To get a summary of the procedures across all databases in your system, use SHOW PROCEDURE STATUS.

Using the \G option outputs in rows instead of columns.

mysql> DELIMITER //
mysql> CREATE PROCEDURE myProc (IN in_count INT)
    -> BEGIN
    ->     DECLARE count INT default 0;
    ->
    ->     increment: LOOP
    ->     SET count = count + 1;
    ->     IF count < 20 THEN ITERATE increment; END IF;
    ->     IF count > in_count THEN LEAVE increment;
    ->     END IF;
    ->     END LOOP increment;
    ->
    ->     SELECT count;
    -> END
