Exactly as I described above.
I know that my English is fatal but"
"To set <cStdOut>, <cStdErr> and <nResult> is necessary to wait inside
hb_processRun() until executed command terminates."
seems to be clear.

You have to read my message once again.
I gave you all necessary information.
You have to use hb_processOpen(), i.e.:
hProccess := hb_processOpen( cExecutable )
if hProccess != F_ERROR
while ( nResult := hb_processValue( hProccess, .F. ) ) == -1
? "waiting for process..."
hb_idleSleep( 1 )
enddo
? "process terminated with result:", nResult
endif
