Character coding

Note Decimal codes 00 to 31 and 127 and higher represent nonprintable control characters and special character codes. 

The DEA number is a unique character code which can be easily verified in most cases. The first two of the nine characters are alphabets. The first alphabet is either an A or B, or alternatively, a P or R the letters A and B designate a dispenser, while the letters P or R refer to a distributor. The second alphabet is derived from the first letter of the registrant s last name or his/ her business name. These two alphabets cannot always be verified. The third to ninth positions from left represent a seven digit number which can be verified. To understand the procedure, an example of DEA AB 0494168 verification is provided here. 

Residues involved in the protein splicing reaction are shown by a single character code of amino acids. N- and C-termini are indicated by NH2 and COOH respectively. 

In line with the situation found previously for the other receptor families, several classification schemes coexist for nuclear receptors. In particular, beyond the NC-IUPHAR system described above, an alternative nomenclature system has been proposed and is currently widely accepted and used by the research community working in this family. This annotation scheme consists of a 3-character code. The first character is a number that designates... 

For the sake of comparison, the 3-character code for the human estrogen receptor subtype a is 3.A.1, whereas the NC-IUPHAR RC would be 4.1.3 EST 1 ERA HUMAN 00.

The contents of these columns are identical so that the user can more easily follow the lines of this very wide table across two pages. The columns give the four-character code number (see page l) assigned to each compound and also indicate when more information about a compound will be found on the following pair of pages. 

More elaborate entries, such as "23CD5", ere occasionally necessary this one denotes the use of a three-electrode cell with an agar bridge, deaeration by both hydrogen and sulfite, and digital data-acquisition. When insufficient information was given to permit completing any part of this three-character code, a dash always appears in the appropriate position, as in the entry "0-0". This permits easy differentiation between, for example, "—0" and "0--". 

ULV has been commonly used as an abbreviation tor ultra-low-volume formulations. The standard GCPF (formerly GIFAP) 2-character code is UL (8). 

CODE(fexf) and CHAR(miinher) perform opposite functions. CODE returns the numeric code (either Macintosh character codes or ANSI character codes for Windows) for a single character or the first character in a text string, CHAR returns the character corresponding to the character code. For example, CODE("a") returns 97, CHAR(36) returns. ... 

Returns the character corresponding to the character code number. 

Returns the character corresponding to the character code number, in either the Macintosh character set or the ANSI character set (Windows). 

You will recognize that both message boxes accomplish the same purpose, the only difference being that the second is somewhat more elaborate, with a title and a question mark. Chr(13) is the character code for a linefeed, so that the message appears on two lines. The general syntax of a message box can be either... 

These codes are market codes designed to be used at point of sale, so that the inventory can be kept up to date to the minute. They are made up of thirteen numeric characters all with a meaning. Note that there are some eight character codes, discussed below. 

In the immune algorithm, the antibody and antigen encoding are binary code, code and character code. There are a few gray coding. Binary search capability, but also has the advantages of simple operation of the cross, variation. Therefore, this paper uses binary coding. 

The following single character codes are used to describe possible amino acid combinations at given positions X (any amino acid), (S, P, T, or A), (G, L, or P), o (G, L,... 

Prolog provides I/O based on characters as well. Predicates with suffix -code use character codes (ASCII), and those with suffix -Char use character atoms. Each predicate comes with two variants with an explicit first argument, indicating the stream, or without one in this case, the standard input or output stream is used.
