Not really.

The behaviour is the same: 2 characters ("_"+" ") are written to screen to enter 1 char (IMHO a "_" would be enough). That also affects the next line (when I want to enter a string of length 32 in the first line the next line is also affected(*) and the first characters are deleted :-( )
The only difference now is, that I can see the first character as "_" (was displayed also a SPACE before).

Or is the current behaviour the intended behaviour?

That is the latest test program:

//zcc +zx81 -startup=2 -create-app -vn -o testgets.bin testgets.c
#include <stdio.h>
#include <zx81.h>

void main(void)
{
  char buffer[80];
  printf("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
  zx_setcursorpos(0,0);
  gets(buffer);
}

(*) That is part of another probem: when the last char of a line is printed, the print position moves immediately to the next line, making formating a text using "\n" complicated: when I do a
printf("32chars\n")
and then a
printf("....")
there is a blank line on screen, because "between" the last char and the "\n" the print position is already moved to the next line, so processing the "\n" does an additional linefeed :-(

And when I do a print  to the lower right screen position, the screen scrolls up. Scrolling and automatic linefeed should only occur, when I want to print PAST the last column or screen position, not AT the last ...

The cursor is "nice to have", but I lived long without any cursor on the Zeddy and was also happy ;-)
So if there is no cursor, that would be ok for me ...
But the other behaviour (too early scroll/auto-linefeed) should be solved (my current workaround is to use only 23 lines/31 chars) ...

I did. Thanks for the new ASCII conversion and the inverted capital letters :-)

The first impression was: OK.
But now the BACKSPACE does not work correctly: it can only be used to delete 1 char, not more characters.
And it leaves SPACES on screen: when I enter
"123BACKSPACE4"
I get on screen
"12SPACE4"

Edit: same behaviour in ANSI mode, but "zx_setcursorpos(0,0);" has no effect ...

Hmm, I just downloaded the latest build, but the behaviour is the same ...

?

Today (using the current build) I also found, that after using BACKSPACE there is garbage in the edited buffer (contains char 8).
Here is a test program for ZX81, which shows the error:

//zcc +zx81 -startup=2 -create-app -vn -o testgets.bin testgets.c
#include <stdio.h>
#include <zx81.h>
#include <string.h>

void main(void)
{
  int i;
  char buffer[80];
  printf("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
  zx_setcursorpos(0,0);
  gets(buffer);
  printf("\n\n\n");
  printf("->%s<-\n", buffer);
  printf("lenght=%d\n", strlen(buffer));
  for (i=0; i < strlen(buffer); i++)
    printf("char %d = %d\n", i, buffer[i]);

}

Thankyou, now it is more celar..
So we have a functional bug *and* a visual bug..  are you concerned for both ?

Could that problem be resolved within the near future?
I have written a web-browser for the ZX81 and would like to use the latest enhancements in ASCII-ZX81 character set conversion (to get less errors 404 when trying to get a file from the web with special characters in its name).
To avoid the BACKSPACE error (when entering the URL) I currently use an old z88dk version without that enhancements :-(

Siggi

Thanks!

PS: Here is the link to "ZeddyFox V1.0": http://forum.tlienhard.com/phpBB3/viewt … &t=714

Thanks.
This problems seems to be solved , but there is another one (SHIFTED CHARS, see other bug report).
