"SET ECHO" error in Win 98SE

[precaud]

I’ve run into an error using the “SET ECHO” function of HTB 8.3 in Windows 98SE. This is used to put a crosshairs at a given X,Y location, which I use for a graphics cursor. The example program for testing it is:

10 GINIT
20 PLOTTER IS CRT,”INTERNAL”
30 GRAPHICS INPUT IS KBD,”KBD”
40 FRAME
50 READ LOCATOR X,Y,S$
60 SET ECHO X,Y
70 GOTO 50
80 END

Line 50 reads the mouse pointer location, and line 60 puts the crosshairs there.

This program works fine in ver 8.3 running in Win XP, but not in Win 98SE. No crosshairs is displayed. I’ve tried it in 2 different machines with the same result.

Any ideas what might be the cause?

Hi Precaud,
Maybe there is another way to do the same (found in HTbasic help, “GRAPHICS INPUT IS” topic)

10 PLOTTER IS CRT,”INTERNAL”
20 GRAPHICS INPUT IS KBD,”KBD”
30 TRACK CRT IS ON
40 FRAME
50 DIGITIZE X,Y,S$
60 PRINT X,Y,S$
70 END

Hi Zerider,

I don’t think that is the same You might have to print it, then erase it (with a negative PEN number), then print it again at a new location.

I heard back from HTB support yesterday, he told me the SET ECHO issue with 98SE was a known bug in 8.3, it was fixed in 9.x. So I installed 9.2 and its working fine.
