| 1 iffit1.i and iffit2.b98 are a test of the C-INTERCAL/cfunge external | |
| 2 calls system. To use the test, use this command: | |
| 3 | |
| 4 ick -ea iffit1.i iffit2.b98 | |
| 5 | |
| 6 What follows is the expected output, annotated to show what causes | |
| 7 each line to be printed. | |
| 8 | |
| 9 Before IFFI... Printed by the Funge program before IFFI is loaded. | |
| 10 0 Printed immediately after IFFI loads; the program then | |
| 11 yields immediately, running the INTERCAL program. | |
| 12 I Printed at the start of the INTERCAL program; tests Y. | |
| 13 2 Printed by the Funge program after (100) is NEXTed to. | |
| 14 This tests NEXTING to an L in the Funge program. | |
| 15 III Printed by INTERCAL after the Funge program does 2R | |
| 16 (i.e. RESUME 2). | |
| 17 IV Tests COMING FROM an L when in mark-mode after a NEXT. | |
| 18 5 Tests NEXTING FROM the INTERCAL program to the Funge | |
| 19 program using X. | |
| 20 VI Tests RESUMING to the INTERCAL program after the NEXT | |
| 21 FROM in the Befunge program. | |
| 22 VII Tests that COME FROMs happen at the end of a command. | |
| 23 8 Tests COMING FROM the INTERCAL program to the Funge | |
| 24 program using C. | |
| 25 IX Tests FORGET using F, and also RESUME after a COME FROM | |
| 26 in the Befunge program. | |
| 27 X This (irrelevantly) tests ONCE in the INTERCAL program. | |
| 28 11 This (likewise irrelevantly) tests that p in Funge has | |
| 29 correctly altered the flow of control. | |
| 30 XII Tests COMING FROM an L when not in mark-mode. | |
| 31 13 Tests variable access using G in the Funge program to | |
| 32 read an INTERCAL variable, also a second marker. | |
| 33 XIV Tests the use of S to set an INTERCAL variable. | |
| 34 15 Tests that CREATEd commands send values correctly. | |
| 35 16 Tests that CREATEd commands send bitwidths correctly. | |
| 36 17 Tests that CREATEd commands send names correctly. | |
| 37 The above three tests test CREATION using A and D. | |
| 38 XVIII Tests that V sets arguments to CREATED commands | |
| 39 correctly, and also that Y correctly reflects the | |
| 40 second time. | |
| 41 | |
| 42 At this point the program should end, having tested all the commands | |
| 43 in the IFFI fingerprint. (Obviously, this is not an exhaustive test, | |
| 44 because, for instance, G was only used to get onespot variables not | |
| 45 twospot variables.) | |
| 46 | |
| 47 It is an interesting challenge to try to figure out how the tests | |
| 48 work, especially given that the Funge program is self-modifying, the | |
| 49 statements in the INTERCAL program don't always do the same thing | |
| 50 every time they're run, and the Funge program modifies the syntax of | |
| 51 the INTERCAL program at runtime. |
