WORD_UNIQUE_C Function

Syntax

Output_String as C = Word_Unique_C(C Source [,C Delimiter])

Arguments

Source: A string containing a series of delimited words or values.
Delimiter: Default = CRLF(). The delimiter that separates the words or values.

Returns

Output_StringCharacter: Returns a list of unique words (case-sensitive) in a delimited string.

Description

Remove duplicate words from a list doing a case-sensitive comparison.

Discussion

The WORD_UNIQUE_C() function generates a list of unique words in a delimited string using a case-sensitive comparison. This means two words spelled the same but with difference case will be considered individually unique. For example:

dim txt as c
txt = comma_to_clf("NO,no,NO")

? word_unique_c(txt)
= NO
no

The result of performing a WORD_UNIQUE_C() search on the character list "NO,no,NO" results in a list of two words: "NO" and "no". While both words are spelled the same, they use different cases and are therefore considered to be unique.

For a case-insensitive comparison, use the WORD_UNIQUE() function.
