Line continuation character

If you type a long VBA expression, it will not wrap to the next line but wiU simply disappear off the screen. You will have to insert a line-continuation character (a space followed by the underscore character followed by RETURN) to cause a line break in a line of VBA code, as in the following example ... 

The line-continuation character can t be used within a string. 

This record can appear only once in a file and it may occupy more than one line. The second and subsequent lines contain a continuation field, which is a right-justified integer followed by a blank character. This number is incremented by one for each additional line of the record. Several records belong to this categoi y, e.g., AUTHOR (contains names of the people responsible for the contents of the flic), KEYWDS (contains a list of keywords describing the macromolcculc),... 

Statements. Most statements, except where noted otherwise, begin in the seventh column of a page considered to be 80 columns w ide continuation linen are indicated by a + (symbol may vary with version of language) in the sixth column. The first five columns are reserved for labels (line numbers), which are only required if the line is referenced by another statement, and for comment lines, which are determined by a character in the first column. Columns 7 to 72 are reserved for statements 7.S-80 are not read. (See Table 1-24 for required order of statements in FORTRAN.)... 

The character and the degree of automation in chemical control may have been covered in the above treatment of semi-automatic or completely automatic, and of discontinuous or continuous analysis, but something more should be said about the means by which automation proper has been performed in recent times. Whereas in the past automated analysis involved the use of merely, mechanical robots, to-day s automation is preferably based on computerization in a way which can best be explained with a few specific examples. Adjustment knobs have been increasingly replaced with push-buttons that activate an enclosed fully dedicated microcomputer or microprocessor in line with the measuring instrument the term microcomputer is applicable if, apart from the microprocessor as the central processing unit (CPU), it contains additional, albeit limited, memory (e.g., 4K), control logics and input and output lines, by means of which it can act as satellite of a larger computer system (e.g., in laboratory computerization) if not enclosed, the microcomputer is called on-line. 

The next example, shown in Fig. 4.6a, is the amusing consequence of continually increasing the concentration of background salt (beyond its aqueous solubility—just to make the point) to the shape of log /J/pH profile for acebutolol (whose normal 0.15 M salt curve [362] is indicated by the thick line in Fig. 4.6a). The base-like (cf. Fig. 4.3a) lipophilicity curve shape at low levels of salt can become an acid-like shape (cf. Fig. 4.2a) at high levels of salt An actual example of a dramatic reversal of character is the ionophore monensin, which has a log P (in a background of Na+) 0.5 greater than logP [276,281]. 

From the comparison of the spectra with calculated one-electron density of states curves (lines I and II), therefore, the valence band spectra of U, from photoemission and BIS, are interpreted as due to a hybridized (d, f) continuous band, with a much large itinerant 5 f contribution than in Th for the occupied part . As for the broad structure at about 2.5 eV, qualitative agreements point to a 6d character. 

In this line, resistor R1 is defined as a resistor connected from node 1 to node 2 with a value of 100 2. Several rules apply in defining components. Node 0 is reserved for ground. All circuits must have at least one ground connection. Also, reference designators are limited to alphanumeric characters (Fig. 2.2). Longer statements may be continued on the following line by using a + symbol as the first character to indicate a continuation from the previous line. 

Two lines of inquiry will be important in future work in photochemistry. First, both the traditional and the new methods for studying photochemical processes will continue to be used to obtain information about the subtle ways in which the character of the excited state and the molecular dynamics defines the course of a reaction. Second, there will be extension and elaboration of recent work that has provided a first stage in the development of methods to control, at the level of the molecular dynamics, the ratio of products formed in a branching chemical reaction. These control methods are based on exploitation of quantum interference effects. One scheme achieves control over the ratio of products by manipulating the phase difference between two excitation pathways between the same initial and final states. Another scheme achieves control over the ratio of products by manipulating the time interval between two pulses that connect various states of the molecule. These schemes are special cases of a general methodology that determines the pulse duration and spectral content that maximizes the yield of a desired product. Experimental verifications of the first two schemes mentioned have been reported. Consequently, it is appropriate to state that control of quantum many-body dynamics is both in principle possible and is... 

Gaseous emission of Infrared radiation differs in character from solid emission in that the tenner consists of discrete spectrum lines or bands, with significant discontinuities, while the latter shows a continuous distribution of energy throughout the spectrum. The predominant source or molecular radiation in the infrared is the result of vibration of the molecules in characteristic modes. Energy transitions between various stales of molecular rotation also produce infrared radiation. Complex molecular gases radiate intricate spectra, which may be analyzed to give information of the nature of the molecules or of the composition of the gas. 

Table 9.21 shows a simple FORTRAN computer source program INVERT, to invert 3x3 matrices. The source program is written in "Hollerith card image" format instructions must be between columns 7 and 72 a character in column 6 indicates that the line is a continuation of the previous line comment lines have "C" in column 1 (these are instructive but not essential). Table 9.13 shows the input data, and Table 9.14 shows the output data. Of course, the INVERT program would be much shorter in C+-1- ...
