Dear all,

I use SMath for quite some time now, however I have a very basic question about an input issue that annoys me from time to time.
This is probably the most basic question ever asked on this forum ;-)

When I make a new calculation sheet with the following input, I always get the error "parameter a2 not defined":

a.1:=2m (subscripted variables are used here)
a.2:=3m
a.1+a.2=error

I get this error every time in this specific case, the input happens fast as I'm used to the input procedure.
The TAB-key has been used for confirmation, but for the unit input (m) as for the variable input (a.1 & a.2).

When I save the above file containing the error and reopen it, a.2 is depicted as a2 so without the subscript.
Which mechanism could be at the source of the above behaviour?

Thanks in advance for any feedback!

Kind regards from a true SMath-fan,

Jan Claeys (Belgium)

I experienced the same issue myself several times (both in desktop and android app versions), although I've not yet found a clear way to reproduce it.

Good evening Davide,
Thank you for your swift reaction!
Hopefully, the programming team can pinpoint the exact mechanism behind so that user safisfaction can be increased. If I could, I would resolve the issue myself but my programming skills are insufficient I'm afraid...
SMath is really a beautiful tool and it's popularity will undoubtly further increase.
Kind regards,
Jan

File missing ... since which Smath version ?
Subscript not recognized may have to do with the keyboard style.

Hello Jean,
I didn't attach a file since the issue is so straight forward. I could attach a file Tomorrow?
Since I can perform the input as I want, the keyboard used doesn't seem to be the problem here? The problem has to do with the way parameters are stored and recalled in the program itself? Maybe a compatibility issue with certain extensions?
This problem really grasped my attention in the 3 most recent versions, but is probably much longer present.
Kind regards,
Jan

File not needed because NO bug SS 6179

I use the german settings, which means comma as decimal symbol and semicolon as argument separator.

Sometimes I opened a file and was wondering about the unexpected results in the sheet. Then I found that the last entered decimal symbol, somewhere at a definition, was lost. Maybe that's the same issue.
But I didn't find a regularity.

Hello [USERLINK]janclaeys[/USERLINK].

Thank you for the report. I will try to analyze a code to see what could cause this issue. First impression is that it is something related to multi-threading.
Thanks all for details!

Best regards.

Confirmed no bug. Get a QWERTY keyboard, set English US.

Copy the blue from page 3 ... paste page 14 [gray].

Dear all,

Thank you for the feedback!
@Andrey: thank you! I hope you can trace the concerned background process successfully. FYI: I use the most recent Windows incarnation (Windows 10 Pro; build 19041.508)
@Jean: it's a bug without any doubt (although not always repeatable), please see the screenshot below



Kind regards,

Jan

Collab NDTMA reported no bug latest SS.
I reported no bug SS 6179.
If a bug had appeared past SS 6179, it would have been reported.
It's your system/installation, end of it.
Go to the store, purchase:
1. QWERTY keyboard [English US]
2. a wired mouse, install
Wireless mouse is source of problem(sssssss) !
Your snippet can't be reproduced because there is no bug.
Cheers ... Jean

Hi. I can't reproduce the bug, but it could be interesting to know if, in the case you have the error, if you can see the tooltip about the variable value, as in the image. Isolated or when you write it into an expression. Obviously, autocalculation must to be on.



Best regards.
