Well, I've found a solution to get the .EXE files to work right. You need to use CONVERT/FDL to convert the received file to a fixed block file again. The file CON.FDL is shown below: RECORD FORMAT fixed SIZE 512 For the given example, you type: $CONVERT/FDL=CON BLAH.EXE BLAH1.EXE and BLAH1.EXE will be executable. Oh, you also need to send it with the command: $SEND/FILE/BINARY/NETDATA BLAH.EXE. Stewart Baker Manager, VLSI Texas A&M University SDB5442@TAMVENUS

You are right, receive does mess up the file and record attributes... It
is a simple (?) matter to correct though, using the DCL convert command.
Below is the needed FDL file used in a run, showing that it actually will
work right. Note that I send the file with the /netdata and the /binary
switches to make absolutely sure that no lines are wrapped and no control
characters are stripped, and receive it with /binary and /special to make
sure that nothing else is lost during the receive (CMS I beleive will do
netdata binary format so this should be no problem for your application).
You can type in the FDL file by hand in an editor, but that is hard work!
I suggest you consult a manual to learn how to use EDIT/FDL instead... or
just try using it without the manual -- it is menu driven and fairly easy
to figure out on your own (that is how I did it!)
