success: Boolean;
a: HCkJsonArray;
s: PWideChar;
sb: HCkStringBuilder;

begin
success := False;

a := CkJsonArray_Create();
success := CkJsonArray_Load(a,'[ 1,2,3,4 ]');

// We could get the JSON array as a string...
s := CkJsonArray__emit(a);
Memo1.Lines.Add(s);

// But what if the JSON array contains a huge amount of data,
// and we don't want to marshal it all from Chilkat's internal
// native code to a string in our programming language?

// You can instead emit to a Chilkat StringBuilder
sb := CkStringBuilder_Create();
CkJsonArray_EmitSb(a,sb);

// Perhaps the StringBuilder object can be passed to other methods..
// Chilkat typically provides methods where a potentially large string
// can be passed in via a StringBuilder object..

// Or perhaps you wish to save to a file..
success := CkStringBuilder_WriteFile(sb,'c:/temp/qa_output/a.json','utf-8',False);

CkJsonArray_Dispose(a);
CkStringBuilder_Dispose(sb);
