In the case of ExecuteProcess() parameter separation
takes place on FPC side, while with  fpSystem()  the
shell  is  responsible for it.  Could a problem with
FPC's  parameter  separation  algorithm  be  causing

Can you post both the commands you are executing?

When I was learing processes, I wrote a unit to exe-
cute  a   command   using   fpExecv   --   just   as
ExecuteProcess() does. I'll dig it out and we'll see
how (and whether) it works with your examples.
