Here your telling the compilar that the address where the data is stored
is constant or in other words your not dynamically allocating the memory
for LastName and thus changing the pointer. The data at the address that
LastName points to can change, the address can't.

FldInsert is expecting a void* so the compiler has to cast off the const
but if you explicitly cast gPreson.LastName to a void* this will get
ride of the warning. As long as FldInsert is not changing the pointer
your okay.

Make sure you include Common.h which declares VoidHand and UInt which is
most likely why you get this error. (The compilar does not know what a
UInt is.) Also, UInt and VoidHand have changed to UInt16 and MemHandle
in the 3.5 SDK.

GetObjectFormActiveForm? I don't think this is defined in the API so all
undeclare protypes revert to passing back integer. Go back to the sample
files and look to see if you need to copy this function from the source
code.
