Converts all letters in a string to lowercase.
Syntax
NewString :=   Text.LowerCase(String: Text)
Note
This method can be invoked without specifying the data type name.
Parameters
String
 Type: Text
The string that you want to convert to lowercase. Only letters in the range A to Z and, if applicable, special language characters are converted.
Return Value
NewString
 Type: Text
The string converted to lowercase.
Remarks
Because the Text.LowerCase method is culture-variant, its behavior may vary across different locales. For example, certain characters in languages such as Turkish or Greek may be transformed differently based on regional linguistic rules. For culture-invariant method check Text.ToLower()
Example
var
    Str: Text[60];
    Lower: Text[60];
    Text000: Label 'The Entries are Sorted by Name.';
    Text001: Label 'The string before LowerCase is:>%1<';
    Text002: Label 'The string after LowerCase is:>%1<';
begin
    Str := Text000;  
    Message(Text001, Str);  
    Lower := LowerCase(Str);  
    Message(Text002, Lower);  
end;
The first message window displays the following:
The string before LowerCase is:
>The Entries are Sorted by Name.<
The second message window displays the following:
The string after LowerCase is:
>the entries are sorted by name.<
