The default value is 0, which results in default spacing between letters.

Example

The following handler increases the current character spacing of the third through fifth words

within the text cast member myCaption by a value of 2:

on myCharSpacer

mySpaceValue = member("myCaption").word[3..5].charSpacing

member("myCaption").word[3..5].charSpacing = (mySpaceValue + 2)

end

charToNum()

Syntax

(stringExpression).charToNum

charToNum(stringExpression)

Description

Function; returns the ASCII code that corresponds to the first character of stringExpression.

The

charToNum() function is especially useful for testing the ASCII value of characters created by

combining keys, such as the Control key and another alphanumeric key.

Director treats uppercase and lowercase letters the same if you compare them using the equal sign

(

=) operator; for example, the statement put ("M" = "m") returns the result 1 or TRUE.

Avoid problems by using

charToNum() to return the ASCII code for a character and then use the

ASCII code to refer to the character.

Examples

This statement displays the ASCII code for the letter A:

put ("A").charToNum

-- 65

The following comparison determines whether the letter entered is a capital A, and then navigates

to either a correct sequence or incorrect sequence in the Score:

on CheckKeyHit theKey

if (theKey).charToNum = 65 then

go "Correct Answer"

else

go "Wrong Answer"

end if
