+## 1990 jaw
+
+### STATUS: known bug - please help us fix
+### Source code: [1990/jaw/jaw.c](1990/jaw/jaw.c)
+### Information: [1990/jaw/README.md](1990/jaw/README.md)
+
+[Cody Boone Ferguson](https://www.ioccc.org/winners.html#Cody_Boone_Ferguson)
+fixed some issues in this program and [Yusuke
+Endoh](https://www.ioccc.org/winners.html#Yusuke_Endoh) provided the `btoa`
+script but it appears there is a bug in this entry. The judges wrote that to
+test the entry one can do:
+
+```sh
+echo "Quartz glyph jocks vend, fix, BMW." | compress | ./btoa | ./jaw
+```
+
+which should apply the identity transformation to a minimal holoalphabetic
+sentence.
+
+But doing this shows instead:
+
+```sh
+echo "Quartz glyph jocks vend, fix, BMW." | compress | ./btoa | ./jaw
+a얖?)V...?????777??hC??h??-?	)SSSSXXX????r?L=???*?-???ppp,,,?R
+?j
+111-)))? '..F@E
+               ???b111?
+..F..F.?n,,,,,L@E$
+```
+
+Notice how there's no newline at the end: that final `$` is the prompt.
+
+If one does, however:
+
+```sh
+echo "Quartz glyph jocks vend, fix, BMW." | compress | ./btoa | ./jaw | ./jaw
+```
+
+they will get just
+
+```
+oops
+```
+
+which seems to be an error message (one of the fixes was to make it not use
+`perror(3)` - this fixed something else though it's no longer known what).
+
+The script [shark.sh](/1990/jaw/shark.sh) has some issues too in that due to
+path not having `.` (this and maybe some other things were fixed) and `tar` not
+wanting to accept reading from `stdin` (this in particular) even with the right
+options used, seemingly, it has to write to disk the tarball which seems to
+defeat the purpose. This would ideally be fixed.
