| 294.1 | ^Z Works Independently of CDU | VAXUUM::DYER | Define `Quality' | Mon Aug 25 1986 21:04 | 7 |
| The CDU itself doesn't handle ^Z. Typically what one does
is use lib$get_input() to read a command into a buffer, then
run CLI$ routines on the text in that buffer.
What happens when you type ^Z is that lib$get_input() will
return a status code of RMS$_EOF instead of SS$_NORMAL. You
check the status and act accordingly.

| 294.2 | Use SMG$ routines | FROST::HARRIMAN | ACK Phfft! | Thu Aug 28 1986 10:12 | 9 |
|
The best way I know of to make ^Z be recognized is to use the SMG$
routines directly. You can define your termination characters using
the routine SMG$READ_STRING. Read the manual-page 5B/RTL-599. You would,
of course, have to use all of the other SMG$ functions too, but
they are very easy to master for simple (one keyboard, one display)
applications.

| 294.3 | Either Works - LIB$'s Easier - SMG$'s More Powerful | CLOSET::DYER | Define `Quality' | Fri Aug 29 1986 15:37 | 6 |
| If it's just ^Z you want to recognize, LIB$GET_INPUT will
do that very well, returning RMS$_EOF status when ^Z is typed.
If you need more terminating characters besides the usual,
SMG$READ_STRING is useful. (I use it for TOPS-20 like incre-
mental help, when the `?' key is typed.)
