Hi,

I'm Trying to compile a TTCN-3 script but getting error.
The constructs for which error is being generated seems to be valid TTCN-3 Syntax.
I'm attaching the script and the build log.
Please help.

Thanks
Murli

Hi Murli,

The attached make.log shows your input file RLC_r3_wk37.ttcn does in fact include syntactical errors. Find first "error" string in "make.log", open the referenced file, go to indicated line number and you find what is wrong with the input. The error message given by the parser attempt to provide hints.

In this particular case, the first error is:

RLC_r3_wk37.ttcn:4186.23: error: Character `@' (0x40) is not used in TTCN-3

The referred line looks like:

external function @deterministic o_HexToDigitsMCC(hexstring p_BCDdigits) return MCC;

In my understanding the symbol @ is invalid to use in TTCN-3 identifiers. It appears that your TTCN2 to TTCN-3 converter includes the @deterministic tag for some reason. I believe TITAN does not understand this.

In fact I am not sure if the @deterministic tag conforms to TTCN-3 standard or if it is valid in this context.

You are right, they are valid TTCN-3 construct according to the latest version of the standard, but not yet supported by the TITAN

Hi Murli,

not in the near future, meaning not in H1 of 2016.

Best regards

Can you tell me which version of TTCN-3 does Titan supports?

Thanks

Hi Murli,

we are preparing a detailed SoC in response to this question ; there is no unambiguous answer: some elements of 4.6.1 are already supported, but there might be parts of earlier editions which are not;
besides, there's a ton of features on top of the standard.
we have developed Titan based on requests from our internal customers which did not necessarily follow the standard.

In your concrete case, the workarounds are quite straightforward;
the @deterministic can be removed as it has no practical impact;
the reception into a partial variable can be changed to a reception into a full variable.

Best regards

Elemer

Hi Elemer,

We're trying to procure a TTCN-2 to TTCN-3 converter. So we need to know what TTCN-3 features Titan won't support.
Can we get a comprehensive list of such features? By when can you help us in getting such a list?

Also do you have any tool to convert TTCN-2 to TTCN-3 ?

Thanks
Murli

Hi Murli,

we are preparing a detailed SoC (Statement of Compliance ) for part I of the standard.; this should be ready H1 of this year.
As I mentioned earlier, few years ago we have participated in a number of TTCN-2 to TTCN-3 conversion projects, and in our experience there's no fully automated conversion method ( that I know of anyhow);
Automatic conversion will only take you part of the way, and a lot has to be done manually.

We don't have such a tool at present.

Best regards
Elemer
