TokenLower()

Change the first letter of tokens to lower case

Syntax

      TokenLower( <[@]cString>, [<cTokenizer>], [<nTokenCount>],
                  [<nSkipWidth>] ) -> cString

Arguments

<[@]cString> is the processed string

[<cTokenizer>] is a list of characters separating the tokens in <cString> Default: chr(0) + chr(9) + chr(10) + chr(13) + chr(26) + chr(32) + chr(32) + chr(138) + chr(141) + “, .;:!\?/\\<>()#&%+-*”

[<nTokenCount>] specifies the number of tokens that should be processed Default: all tokens

[<nSkipWidth>] specifies the maximum number of successive tokenizing characters that are combined as ONE token stop, e.g. specifying 1 can yield to empty token Default: 0, any number of successive tokenizing characters are combined as ONE token stop

Returns

<cString> the string with the lowercased tokens

Description

The TokenLower() function changes the first letter of tokens in <cString> to lower case. To do this, it uses the same tokenizing mechanism as the token() function. If TokenLower() extracts a token that starts with a letter, this letter will be changed to lower case.

You can omit the return value of this function by setting the CSETREF() switch to .T., but you must then pass <cString> by reference to get the result.

Examples

      ? TokenLower( "Hello, World, here I am!" )         
                    // "hello, world, here i am!"
      ? TokenLower( "Hello, World, here I am!",, 3 )     
                    // "hello, world, here I am!"
      ? TokenLower( "Hello, World, here I am!", ",", 3 ) 
                    // "hello, World, here I am!"
      ? TokenLower( "Hello, World, here I am!", " W" )   
                    // "hello, World, here i am!"

Tests

      TokenLower( "Hello, World, here I am!" )         
               == "hello, world, here i am!"
      TokenLower( "Hello, World, here I am!",, 3 )     
               == "hello, world, here I am!"
      TokenLower( "Hello, World, here I am!", ",", 3 ) 
               == "hello, World, here I am!"
      TokenLower( "Hello, World, here I am!", " W" )   
               == "hello, World, here i am!"

Compliance

TokenLower() is compatible with CT3’s TokenLower(), but a new 4th parameter, <nSkipWidth> has been added for synchronization with the the other token functions.
