Predefined Global Alpha Labels
There are a few labels employed and provided for particular tasks already. You find
them listed in CAT when the respective routines are loaded in XROM. Thus they will not
take any steps from user program memory.
Provides the step size for differentiation. See f f in the Index of Opera-
tions for more information.
More routines are found at http://wp34s.svn.sourceforge.net/viewvc/wp34s/library/ as
text files with extension .wp34s by convention. This includes, for example, a suite of ba-
sic 3D vector operations, a TVM application, and more. You may open these files using
e.g. Notepad, and download them following your needs. README_ASM explains the
loading procedure.
MESSAGES
There are some commands generating messages, also in the dot matrix section of the
display. Four of them, DAY, DAYS+, STATUS, and VERS, were introduced above in the
paragraph about display already. Others are PROMPT, VIEW and many more alpha
commands, and the test commands as mentioned above.
Also two constants will return a special display when called: NaN and will show
or , respectively.
Furthermore, there are a number of error messages. Depending on error conditions, the
following messages will be displayed in the mode(s) listed:
Invalid date format or incorrect date in input,
e.g. month >12, day >31 etc.
Invalid digit in integer input, e.g. 2 in binary, 9
in octal, or +/- in unsigned mode.
Caused by calling an operation in a mode
where it is not defined, e.g. SIN in hexade-
cimal.
