  No, a ^Z from a terminal is translated to End Of File and that info is re-
turned to the application. If your VMS terminal type is set to one the models
that has an F10 key, the terminal driver maps F10 to EOF (note - not to ^Z).

  There isn't an easy way to supply multiple EOF's to a program via a .COM
file (a single one is easy, you generate it when the next input line in the
.COM file starts with a $).

  You probably want to investigate the PTY (pseudo-terminal) services in re-
cent VMS versions (5.4 and up, I think). This will let you run the program
on a pseudo-terminal, which you can control the input/output for.
