Test matrix, should print "matrix works!" and not "broken!".
|
|
|
|
```
|
|
:get-next n:dec dup fetch ;
|
|
:broken 'broken s:put nl ;
|
|
#3 #1 'tester matrix
|
|
get-next #3 -eq? [ broken ] if
|
|
get-next #1 -eq? [ broken ] if
|
|
'matrix_works!_at_ s:put n:put nl
|
|
```
|
|
|
|
Test matrix<xs>, should be "contained!" thrice.
|
|
|
|
```
|
|
#30 #20 #10 #3 #1 'tester matrix<xs>
|
|
{ tester #2 + #3 [ fetch-next swap ] times drop }
|
|
[ { #10 #20 #30 } a:contains? [ 'contained! s:put sp nl ] if ] a:for-each
