In most of life, coercion is such a bad thing it s often illegal, but it s not only a positive thing, but also a highly welcome one in AppleScript, where a coercion is an expression that changes one type of data to another type For example, when you need to change a real number or an integer number to a string, you use a coercion to make the change In many cases, AppleScript performs any necessary coercion for you automatically, drawing your attention to it only if an error occurs for example, because your code needs to coerce data into a data type in which it will not fit You can also coerce data manually to a particular data type whenever you need to To apply a coercion, you use the as operator and the data type you want For example, the following commands create an integer variable named myInteger with the value 100, and then use as string to coerce the value of myInteger to a string The result is "100" (including the double quotation marks that indicate a string)

If I were writing a resume-searching application, this could come in handy. The last option I want to cover here is the NEAR keyword, which looks for two words in close proximity to each other:

alias alias boolean boolean boolean class class constant constant date date file file integer integer integer item from list List Text Integer List Text List Text List Text List Text List Text List Real Text [various] Returns a single-item list Returns a text string Returns 1 for true and 0 for false Returns a single-item list, either {true} or {false} Returns a string, either "true" or "false" Returns a single-item list Returns a string Returns a single-item list Returns a string Returns a single-item list using the format shown in International preferences for example, {date "Thursday, April 1, 2010 6:44:03 AM"} Returns a string using the format shown in International preferences for example, "Thursday, April 1, 2010 6:44:03 AM" Returns a single-item list Returns a text string Returns a single item list for example, {150} Returns a real number for example, 1500 Returns a string containing the integer s value for example, "150" You can coerce the list item to any class to which you can coerce an individual item of that class For example, if you have a list of aliases, you can coerce them to text {"Morning", "Afternoon", "Night"} as string returns MorningAfternoonNight Returns the integer portion of the number Returns a single-item list containing the number for example, {17824} Returns a real number for example, 17824 Returns a string containing the number for example, "17824" Returns a single-item list Returns a string Returns the integer part of the number for example, 17824 as integer returns 179 Returns a single-item list for example, {17824} Returns a list with the labels removed For example, {name:"Roofer", animal:"Dog", breed:"Terrier"} as list returns {"Roofer", "Dog", "Terrier"}

In the diode as shown in Figure 19-3, electrons can move easily in the direction opposite the arrow, and holes can move easily in the direction in which the arrow points But current cannot, under most conditions, flow the other way Electrons normally do not move with the arrow, and holes normally do not move against the arrow If you connect a battery and a resistor in series with the diode, you ll get a current to flow if the negative terminal of the battery is connected to the cathode and the positive terminal is connected to the anode, as shown in Fig 19-4A No current will flow if the battery is reversed, as shown in Fig 19-4B (The resistor is included in the circuit to prevent destruction of the diode by excessive current) It takes a specific, well-defined minimum applied voltage for conduction to occur through a semiconductor diode This is called the forward breakover voltage Depending on the type of material, the forward breakover voltage varies from about 03 V to 1 V If the voltage across the junction is not at least as great as the forward breakover voltage, the diode will not conduct, even when it is connected as shown in Fig 19-4A This effect, known as the forward breakover effect or the P-N junction threshold effect, can be of use in circuits designed to limit the positive and/or negative peak voltages that signals can attain The effect can also be used in a device called a threshold detector, in which a signal must be stronger than a certain amplitude in order to pass through

CONTAINS and FREETEXT have two cousins CONTAINSTABLE and FREETEXTTABLE. They return KEY and RANK information, which can be used for ranking your results:

To change the text in the text range, use a set statement with the content property of the text object class For example, the first of the following statements assigns to the variable para1 the text range object of the first paragraph of the active document The second statement sets the content of para1 to New Industrial Policy, a carriage return, and its existing contents, thus creating a new paragraph before the existing first paragraph:
