* Unlock the Chilkat API.
* Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
* by calling UnlockBundle.  It requires a Bundle unlock code.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Global')

lnSuccess = loChilkatGlob.UnlockBundle("Anything for 30-day trial.")

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

* Load the .p7b from a file.
