I am not 100% sure, but I believe it is the act (or operation) of converting
parameters to a called function from one format to another.  For example, OS/2
is a 32 bit operating system.  When it was first introduced, it was a 16
bit operating system.  So software written today in the 32 bit mode must be
'thunked' before calling the old 16 bit routines that were created in the
1st version of OS/2.  A Windows NT program does the same thing when it is
run under Windows 3.1 with the Win32.dll (the Win32.dll performs the
thunking, among other things).
