LBB on Windiw11 with Intel Ultra 9 processor

[gianni]

Good morning, Mr. Russell,


=== LBB TEST ===
I removed all the LBB.exe files from my computer.
I checked that the "automatic test.lbb" program wouldn't run to make sure it wasn't launching any hidden LBB.exe.
I downloaded the LBB.exe file from https://www.bbcbasic.co.uk/lbb/ (16:33:26 on March 29, 2026)
and placed it in the C:\LBBooster directory. I ran it as administrator.
In the properties of the "automatic test.lbb" program, I associated it with this LBB.exe I just downloaded.
Unfortunately, with this latest version of LBB.exe, I haven't noticed any changes in behavior on Windows 11
on computers with an Ultra 9 processor:
Changing the length of the assigned string:
tara$="12345678901234234"
or changing the comment:
'tira$="12345678901234567"
The execution time changed from 530ms to 4300ms.
The same thing happens with automatic test.exe.

=== TEST BBC4W ===
I copied the "automatic test.lbb" program from the LBB Pane to the BBC4W demo IDE.
I fixed the line:
HIMEM=PAGE+&1F400000:INSTALL @lib$+"LBLIB.BBCC":PROC_LBinit
To load the LBB LBLIB.BBC library from LBB.
I ran it in the BBC4W IDE.
The time is fixed at about 530 ms even when changing the length of "tare$="12345678901234234""
or the following comment 'tira$="12345678901234567".

Thank you very much for your attention and I send you my warmest regards.
Gianni

I downloaded the LBB.exe file from https://www.bbcbasic.co.uk/lbb/ (16:33:26 on March 29, 2026)

Check directly what version of BBC BASIC your installed copy of LBB is using, by running this one-line program:

Code: Select all

!*HELP

It should output:

BBC BASIC for Windows runtime engine 6.16a

if it is the latest version.

I saw 6.15a

[gianni]

now it is 16a and all is working
Many thanks
Gianni
