Thanks Dave,

But I think you have answered regarding ExecAndWait, but I was asking about the parameters for ExecProg.

I have now realised that I can probably work out the parameters by looking at the UInterfaces file supplied with DCAL for Delphi, so expect that they are as follows:
FUNCTION ExecProg (path, prog, parameters : str255; ret : OUT integer) : integer;

As I noted, the above is what I expect, but could be wrong so would be grateful if you could correct me if required. Also, it is not clear to me what the last parameter (ret) is ... if it is a return code then what is the integer result of the function (which I would have assumed to be the return code)?

Thanks,
David H

p.s. thanks for the information on the WindowState values. I have had trouble finding these values in the past (and just settled on using 1 as it produced the desired result), and had only recently found them in one of your previous responses within this thread.
