     3CCL has an inspector, an interactive tool to let you look at, and in 
     4some cases modify, Lisp objects.  To inspect a Lisp object, call the 
     5function INSPECT on the object.  This displays the object, showing its 
     6contents as a sequence of numbered "items".  If there are a lot of 
     7items (e.g. a large array) , they're displayed in "pages", i.e. groups 
     8that you can scroll up and down through.  (Each "page" is 20 lines.) 
     9 
     10It enters a read-eval-print loop that understands the following 
     11top-level commands: 
     12 
     13=== {{{(:i N)}}} === 
     14 Inspect the N'th item, entering the inspector recursively. 
     15 
     16=== {{{:pop}}} === 
     17 Exit the current inspector level. 
     18 
     19=== {{{:show}}} === 
     20 Show (display) the object being inspected, again. 
     21 
     22=== {{{:next}}} === 
     23 Show next "page" of the object 
     24 
     25=== {{{:prev}}} === 
     26 Show previous "page" of the object 
     27 
     28=== {{{:home}}} === 
     29 Show first "page" of the object 
     30 
     31=== {{{(:s N V)}}} === 
     32 Set the value of the N'th item to V, where that can be done. 
     33 
     34 
     35If you type in an ordinary Lisp form, it is evaluated and printed. 
     36The variable {{{ccl::@}}} is bound to the object being inspected. 
     37 
     38In the {{{:i}}} and {{{:s}}} commands, N is not evaluated, and in the {{{:s}}} command, 
     39V is not evaluated.  (You can use the {{{#.}}} reader macro if you do 
     40want to get something evaluated in those positions.)
