pforth under OpenVMS

[TheFausap]

Hello, I was able to compile pforth under OpenVMS 9.2 (x86_64), but I have only a slight issue with the terminal. I can't use the POSIX io file, because I do not have termios, so I opted for the stdio. What's happening is a sort of problem with the screen buffer, if I understood correctly:

$ run pforth
PForth V2.0.1, LE/64, built Feb 23 2023 10:40:00 (static)

123 567 +
123 567 +    ok
Stack<10> 690

my input is repeated before the ok. I don't exactly where is, in the code, the relevant part, so if I you could point me in the right direction, this will be appreciated.

thanks a lot, Fausto

Echoing is done by sdTerminalEcho(), which is a NOOP in stdio.c. So that should not be causing the echo.

Try entering: ECHO @ . 0 ECHO !

That controls another type of echoing at the level of the outer interpreter.

When you are first typing a line, do you see each character appear as you type?

OpenVMS is interesting. I once wrote a Forth in VAX Assembly code. The VAX was a nice machine.

Look for "echo" in this file: https://vmssoftware.com/docs/VSI_C_RTL_REF_MAN.pdf

Yes, I see the characters as I type them. This is the output from the commands above:

$ run pbfth
PForth V2.0.1, LE/64, built Feb 23 2023 10:40:00 (static)

ECHO @ .
ECHO @ . 0    ok
Stack<10>
0 ECHO !
0 ECHO !    ok
Stack<10>

I will check in the refman for the echo.

thanks!
