- No, SET TERMINAL/INQUIRE does NOT "flush the command buffer." It flushes the
- typahead buffer of the terminal you're setting. Now, if SYS$COMMAND happens to
- be that terminal, then any typeahead will, indeed, be flushed and you might
- lose commands that immediately followed the SET TERMINAL/INQUIRE. However, if
- SYS$COMMAND is, for example, a DCL procedure, then you don't lose any
- subsequent commands. The original poster didn't make it completely clear, but
- it looked to me as if he was talking about the latter case.
