Character Functions
• a list, length returns the number of items in the list;
• a blob (binary object), the number of bytes.
Num
Produces a numeric value that corresponds to its character string argument when the character string
consists of numbers only. If a character string contains a non-numeric value, the result is a missing value.
For example, Num(“1.123”) evaluates as 1.123.
Substr
Extracts the characters that are the portion of the first argument. Begins at the position given by the second
argument, and ends based on the number of characters specified in the third argument. The first argument
can be either a character column or a literal value. The starting argument and the length argument can be
numbers of expressions that evaluate to numbers. For example, to show the first name only,
Substr("Veronica Layman", 10, 6) starts at position 11 and reads through position 16, which yields Layman.
If start is negative, Substr searches backward from start from the end of the string. If length is negative or
absent, Substr returns a string that begins with start and continues to the end of s.
Substr can also be used with lists.
Trim
Produces a new character string from its argument, removing any trailing blanks. For example, Trim("john ")
evaluates as john.
Word
Extracts the n th word from a character string. One or more spaces define where each word begins and ends
unless the optional delimiters argument is specified. For example, Word(2, "Veronica Layman") returns the
word Layman.
To insert the delimiters argument, click on any argument in the Word function and then click the insert
button on the Formula Editor keypad. Use the delete key on your keyboard or the delete button on
the Formula Editor keypad to remove the delimiters argument. If you do not specify a delimiter, space is
used as the delimiter. If you define the delimiter as an empty string, each character is treated as a separate
word.
Most special characters act as single delimiters. You can enter any character or set of characters to act as a
word delimiter. For example, to extract the last name in the following example, use a comma and blank
together as the delimiting characters and ask for the first word. Word(1, "Layman, Veronica", ", ") returns the
word Layman.
Words
Extracts the words from text according to the delimiters listed in the optional second argument. The default
delimiter is space. For example, Words("the quick brown fox") returns {"the","quick","brown","fox"}.
