14 This program should ouput (on a POSIX system):
|
|
|
15 Hi there (and now a ls):
|
|
|
16 <list of files in current directory, as ls outputs it>
|
|
|
17
|
|
|
18 Retval (should be 0): 0
|
|
|
19 Will run: exit 2
|
|
|
20
|
|
|
21 Retval (should be 2): 2
|
|
|
22 GOOD: = pushed -2 on zero length string.
|
|
|
23 There should be no indention in the output. (It was done here for clarity.)
|
|
|
24 The blank lines should match.
|
|
|

|
|
|
26 The last test (value on zero length string) is implementation defined, but
|
|
|
27 cfunge is supposed to push -2. Other implementations may push other values
|
|
|
28 (even 0).
