Note for 64 Bit PCOMM:

Functions like API and Automation that were previously supported using 32-bit applications (eg: MS office 32-bit) will now require 64-bit applications to support the same functions in 64-bit PCOMM. For example, Automation will work only using 64-bit version of MS Office.
The API functions exported by PCOMM, that are used by external applications to communicate with PCOMM, will now need to have their prototypes changed in order to be 64-bit compliant.
For example,
```
Declare Function pcsStartSession Lib "PCSAPI32.DLL" (ByVal buffer As String, ByVal SessionID As Integer, ByVal CmdShow As Integer) As Integer
```
declared in a VB macro script will change to
```
Declare PtrSafe Function pcsStartSession Lib "PCSAPI32.DLL" (ByVal buffer As String, ByVal SessionID As Integer, ByVal CmdShow As Integer) As Integer
```
Note:
The usage of "PtrSafe" keyword marks the function as being 64-bit compliant.
