* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* We have this XML to be compressed and then encoded in Base64.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.FileAccess')
loFac = CreateObject('Chilkat.FileAccess')
lcStrXml = loFac.ReadEntireTextFile("qa_data/ebics/SignaturePubKeyOrderData.xml","utf-8")
* Assuming the above statement succeeded...

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Compression')
loCompress = CreateObject('Chilkat.Compression')

* EBICS wants the deflate algorithm with the zlib header...
