I call an OLE Automation server from a program but I couldn't find a better
way than to implement my own calling interface. Simple but requires a
considerable amount of typing.

I had a lot of headache before I realized that the variables used in the
process have to be aligned on four-byte boundaries and, as FPC does not
provide a means to specify alignment (I don't mean records but plain
variables), I had to pad my important variables manually. Also I found that
it only works if I use the -al switch. I didn't actually investigate why...
