xx LB 4.5 is underwhelming
« Thread started on: Jul 28th, 2015, 7:44pm »

I downloaded and installed the newly announced LB 4.5
I never needed more memory
I don't use these:
INP and OUT on 64-bit Windows
OPEN "COMn:" - Remove restrictions on baud rates
INPUTCSV - New INPUT statement for reading CSV files with quotation marks
HTTPGET$() - Get the contents of a web page

As noted earlier these are easily made functions:
AFTERLAST$() and AFTER$() - Return the part of a string after matching a substring
REPLSTR$() - Replace one string pattern with another
REMCHAR$() - Remove a string pattern from another string
UPTO$() - Match a p

I would have preferred Carl had worked on version 5, instead.

I simply don't understand Carl's priorities. Whenever I release a new version of LBB or BB4W, at the top of my list, by a large margin, is fixing bugs. I give only a very low priority to adding built-in functionality which replicates what can easily be achieved with a user-defined function.

LB 4.5.0 seems to be the opposite. There are several new keywords which simply reproduce what user code can straightforwardly do (and which break compatibility with any existing program that uses one of them as an array name). Yet of the well-known and documented bugs I have tested so far not a single one has been fixed!

why.
It is said that "path limit" in open dialog window has been fixed.
And bug with Paste shortcut (Ctrl V) where text is pasted in another (not active) control is fixed too (actually I requested that fix).

I said "of the ones I have tested" and I didn't try those (I wasn't even aware of the second one).

But my point remains: even something as serious as the TIMER bug - which really impacts on programs, especially because of label scope issues - is unchanged. This program locks up LB 4.5.0 (try moving the IDE window):

Code:
    timer 100, tick
    wait

sub tick
    print "Tick"
end sub

Does the release candidate pose any compatibility issues for LBB and if so will you update LBB to fix that? As alway Thanks Richard.

LBB 3.00 already supports the main new features of LB 4.5.0:
  • The available memory is increased (to 500 Mbytes rather than 1 Gbyte, but LB 4.5.0 does not run at all on my Windows XP PC because 1 Gbyte cannot be allocated).

  • The texteditor control and text window have the !find, !findback, and !resetfind commands.

  • The texteditor control and text window have the !backcolor and !forecolor commands.

  • Boolean expressions are truncated to an integer, so for example the condition if 0.5 is treated as false.

  • The new string functions are not natively supported in LBB 3.00, but are available as a library which can be included in a program (and because LB 4.5.0 ignores the 'include directive this confers full compatibility).
So that really only leaves the new inputcsv statement as something which LB 4.5.0 has but LBB 3.00 doesn't. I could either add that in a future version, or make available a user-defined routine with equivalent functionality.

i wood it liked it more if carl made :
SWAP
SGN()
ATAN2()
INCLUDE
PI , TRUE , FALSE as const
hopefuly he wil do that + OOP in LB5
SWAP , SGN , ATAN2 are also not in LBB300

SWAP and SGN are in LBB 3.00, if you do not mind using the BBC BASIC escape feature:

Code:
    a = 1
    b = 2
    !SWAP a,b
    print a,b 

Code:
    a = -3.14159
    b = 0
    c = +3.14159
    !a = SGN(a)
    !b = SGN(b)
    !c = SGN(c)
    print a,b,c

Richard,

The TIMER bug which they mentioned to on their "Bug tracker" site is more than a SUB routine problem.

If you please run the following modified code on both LB and LBB.

'code----------
timer 100, tick
wait

[tick]
print "Tiiiiick"
wait
'code---------

Actually I got a lot of disappointments from LB.
Now I got that freeze, halted, locked, hangup, or whatever you call it for no sensible reason.
Each time I used Timer in my programs I felt the PC or OS became unhappy, what should I do?
I have to use LBB.
There is no other choice for me.

Regards,
Sarmed

Sarmed you have given the timer a sub handler name but not written the sub. The way to avoid timer issues is to contain any timer delay within its own sub which would appear to fix the scope issue.

Yes, Dear Rod,

I did but LB goes inside the branch label and run it, displays Tiiiick the code is wrong LB accepted, and makes a wrong execution.

I wonder, are you going to make me refuse what I seen on my screen, or you ask me to write correct code because LB accepts and run wrong codes. So we must pay more attention.!

You know what?
I run my code on LBB just to help me find if there were errors I made not reported by LB.

With all respects,
Sarmed

Rod,

As you here, please note.
There is something wrong with timer at least under LB, I have to change any SUB in my program into branch label, just to prevents my program from got freeze after I use many timers, of course I close each one at the beginning of any branch, but this is the only way I have in spite I don't use any SUBs with any timer in my program, the window got freeze when I touched it's capture.
Therefor I said the problem is in Timer not in subs as they said on their bug tracker site.
I hope Carl will take care of that.

Regards
Sarmed

To be fair, sometimes you need to do the opposite! The program you listed should report something like "No such subroutine 'tick'" but in LBB the error is silently ignored. sad

But you are right that in LB 4.04 and LB 4.5.0 the timer has more problems than just the SUB handler. In particular it upsets the operation of the PROMPT statement.

So, since there's obviously something not right with TIMER, I'm not surprised that you have encountered other issues with its use.

Rod,

If you still here please run the following, It is a disaster.
The second release of LB 450 will RUN all the following Branches whatever names they have or quantity.

Please tell Carl I am sure he listen well to you.

'code----------
timer 100, tick
wait

[ticktacktoock]
print "ticktacktoock"
wait

[secondTick]
print "secondTick"
wait

'code---------

I don't think it is a "disaster", but it is certainly surprising and affects not only the timer. Try this program in LB and you'll see that BUTTON events misbehave as well (click on the button three times and watch what happens):

Code:
    UpperLeftX = 1
    UpperLeftY = 1
    button #w, "Click me and view the mainwin", tick, UL, 20, 100
    open "Event bug" for window as #w
    wait
    print "Fell through a WAIT statement: should never happen!!"

[ticktacktoock]
    print "ticktacktoock"
    wait
    print "Fell through a WAIT statement: should never happen!!"

[secondTick]
    print "secondTick"
    wait
    print "Fell through a WAIT statement: should never happen!!" 

I am beginning to think this bug explains the occasional report I have seen of code following a WAIT statement being executed - because it's exactly what happens in this case!

In LBB there is no way the statement immediately following a WAIT can be executed, unless it has a label.
