9999 which is followed by a label name. A label with this label name
100100 is sought in the program and, if found, the position of the label
101101 in the program text (with 0 being the position of the first character
102 of the program, and with all characters, including whitespace, having
103 sequential positions within the program) is written to the register.
104 If there are multiple labels with the same label name, the one closest
105 to the start of the program text is chosen. If a matching label is
106 not found, "an error occurs", whatever that means exactly.
102 of the program, and with all characters, including whitespace and

104 the register. If there are multiple labels with the same label name,
105 the one closest to the start of the program text is chosen. If a

107108 * an _output statement_, which is where the register reference
108109 is followed by a `>` character. The ASCII character with the same
109110 value as the contents of the register will be written to the program's
125126 time a jump statement is executed.
126127 * an _emotion bank switch statement_, which is where the register
127128 reference is followed by a `=` followed by a `>`. The emotion bank
128 is switched to the value in the register. If that emotion bank is
129 not supported by the implementation, "an error occurs".
129 is switched to the value in the register. The previous emotion bank
130 number is then written to the register for posterity. If that emotion
131 bank is not supported by the implementation, "an error occurs". An
132 "error" may also "occur" if emotion bank switching is not supported
133 by the implementation.

230 (While some of the above may not be emotions per se, and while some
231 combinations, such as "faint zeal", "mild rage", and "extreme apathy" may be
232 tricky to express, this does not detract from the bare fact that Cfluviurrh
233 *does* support experiencing emotions.)
234
235234 There are five intensity levels, listed in the following table. To find the
236235 intensity level of an emotion to be experienced, each of the first twenty-six
237236 registers are multiplied by three (modulo five) and this set of values is
255254 just that, you know, it's C.
256255
257256 As mentioned, the reference implementation requires the user to agree to
258 act as the emoter. As it uses standard input and output to interact with
259 the emoter, asking them to agree to act as the emoter, and prompting them to
260 feel the required emotions, the input stream and output stream of the
261 Cfluviurrh program are assigned to two files given on the command line:
257 act as the emoter. As it uses C's standard input and standard output to
258 interact with the emoter, asking them to agree to act as the emoter, and
259 prompting them to feel the required emotions, the input stream and output
260 stream of the Cfluviurrh program are assigned to two files given on the
261 command line:
262262
263263 cfluviurrh <program-file> <input-file> <output-file>
264264
265 When "an error occurs" the reference interpreter exits to the operating
266 system with an error message of some sort.
265 To facilitate interactive Cfluviurrh programs, the input-file and
266 output-file may be named pipes, or (on AmigaOS) console devices, or
267 something.
268
269 When "an error occurs" the reference interpreter generally exits to the
270 operating system with an error message of some sort. Although, it may
271 just crash, too.

268273 Discussion
269274 ----------
282287 "real" parser would not be necessary. I implemented in C partly because it
283288 would be nice to port it to AmigaOS 1.3 someday, and partly because, if I
284289 don't have enough C repos on Github to outnumber my legacy Perl repos,
285 they'll label me a Perl programmer, and I don't particularly want that.
290 they'll label Cat's Eye Technologies a Perl outfit, and I don't particularly
291 want that.

293 While some of the entries in the emotion table may not be emotions per se,
294 and while some combination of intensity and emotion, such as "faint zeal",
295 "mild rage", and "extreme apathy" may be tricky to express, this does not
296 detract from the bare fact that Cfluviurrh *does* support experiencing
297 emotions.

287299 Because every label name can only be a single printable character, it might
288300 appear that the number of jump destinations in a program is limited to 95.
