OK, getting back to being better running the binary in an Obey
for that kind of simplicity then.
My Fetchmail program is in an obey file called by a Taskwindow.
It is well suited for Sys$ReturnCode it can range from O to 16 or so.
0 for mail received, 1 for no mail to retrieve, and higher numbers
reflect various authorisation or network faults.
