Each symbol is composed of the first two letters of the genus+first two letters of the species+first letter of the terminal infraspecific name+tiebreaking number (if needed). Genus and family symbols are the first five (genus) or six (family) letters of the name, plus tiebreaking number (if needed). Symbols were first used in the Soil Conservation Service’s National List of Scientific Plant Names (NLSPN), and have been perpetuated in the PLANTS system.

The -> is the "infix dereference operator". In other words it is the means by which one calls a sub with a pass by reference (among other things you can do with ->). As stated above most things in calls to Perl/Tk routines are passed by reference. The -> is used in perl just as in C or C++. (Most of the widget primitives are elements of the Tk:: "perl class".) A simple example of dereferencing would be: $x = { def => bar }; # $x is a reference to an anon.

REG) By default, symbols are exported using EXPORT_SYMBOL, so they can be used by loadable modules. During the 2.4 series, a new export directive EXPORT_SYMBOL_GPL was added. This is almost the same thing, except that the symbol can only be accessed by modules which have a GPL compatible licence (note that this includes dual-licenced BSD/GPL code). This new directive was added for these reasons: To clarify the ambiguous legal ground on which non-GPL (particularly proprietary) modules lie.

IMPLODE and EXPLODE were functions in old lisps where there was no string data type, so that symbols were the only way of manipulating text. Then (explode 'foo) would give you (F O O); you could then do (implode (cdr (explode 'crash))) to give you back the symbol RASH If you are taught today about implode/explode in a lisp programming class for anything other than historical context, complain loudly to your lecturer.

Inserting icons and symbols is a feature of XL Pro Platinum Edition, Version 6 builds 19.74 and higher. If you do not have build 19.75 or higher, you will need to download the latest version of XL Pro Platinum Edition. Icons and symbols can be inserted by clicking on the "S" on the XL Pro Command Bar. The Symbols and Icons Library pages can be turned on and off at any time.

The elephant represents the Republican Party, and the donkey represents the Democratic Party. Political cartoonist Thomas Nast created both images for the publication Harper's Weekly in 1874. Nast created a marauding elephant to represent the "Republican vote." Republicans quickly embraced the symbol as their party's own.

Yes. The symbols for unknown plants represent generic categories such as ‘deciduous tree’ or ‘herbaceous vine’ that are useful in survey, monitoring, and inventory work. These symbols and associated descriptive names are widely used by a number of federal agencies.

ColorScan's? software is insensitive to changes in scale or comparative size of each symbol. The limitation on the low end is resolution. The limitation on the high end is a function of fitting the entire solution within the 18 inch window (on standard scan zones). Graders are trained to make marks that are about 2 inches. Marks less than 1 inch are not recommended. No, Lucidyne neither manufactures nor sells fluorescent markers.

SI unit names are ordinary words. SI unit symbols are exactly that - symbols - and have fixed forms. Here are some of the differences in usage. Unit names are spelled and pronounced differently in different languages. For example, it's "meter" or "metre" in English, "m?tre" in French, "Meter" in German, and "metro" in Spanish. Unit names are singular or plural as usual - one meter, two meters. (But "one hertz," "two hertz," since the plural of hertz is hertz.

Instructions for typing special characters such as exponents, the degree symbol, and the Greek letter mu depend on your computer's operating system and what particular software you're typing "at," among other things. Following is some general advice; consult your computer's "help" system or other documentation for further assistance.

On the other hand, please make sure that you've built the entire distribution with the same configuration. Not clear ? After running the "configure" command with its options, you should ideally run "make clean". Otherwise e.g. clients/Motif-1.2/mwm/Makefile may be configured such that it looks for stuff that isn't there in lib/Xm/* .

I want to define symbols as register names when writing XA assembler code, but once I've used equ to define a new register name, I can't later use set to redefine that name to something else. A: What happens is this; once you have defined a symbol as a register, it then becomes identical with that register, i.e. this code: areg equ r0 areg set 0 is equivalent to areg equ r0 r0 set 0 which is syntactically incorrect. The way I would do it is to use the C preprocessor, and do #define areg r0 ..

A: This can be due to a few reasons but mostly it is probably due to the particular font I used. Fonts for those that aren't totally sure are the particular script of a letter that is used. There are thousands of different fonts on the net and most computers come with a few core fonts. Some people have some fonts that others don't and that being the case I may have used a font that you don't have.

Heart Icon (Type 'HRT' on the order form, to show us where to engrave your heart. Heart Icons are typically as wide as three letters)

Those particular symbols represent the 'th' in the and the 'th' in three respectively. They belong to the International Phonetic Alphabet (IPA) and you can find out more at:

The ISO Latin codes for all of the "funny symbols" used in Guttag and Horning's handbook are found on page 224 of [Guttag-Horning93]. Type the characters on the right hand side when using LSL. If you are reading the handbook in print form, you might want to tape a copy of that page to your wall. See section 2.25 Where can I find LaTeX or TeX macros for LSL?, for details on how to get your specification to print out like the handbook.
