  • Patch Set #1, Line 2546: case (tr_RSL_ChanMode_SIGN)

    what? you can use templates as cases?

    Yeah, why not? :) ETSI ES 201 873-1 defines the syntax as follows:

    ```
    select "(" SingleExpression ")" "{"
      { case "(" { TemplateInstance[","] } ")" StatementBlock }+
      [ case else StatementBlock ]
    "}"
    ```

    I wonder how is that implemented, given that 2 templates could match the same value...

    I guess the one that matches first wins.

    did you make sure this works as expected?

    Yes. Actually we already do have templates-in-select in our code base:

    ```
    bsc/BSC_Tests.ttcn: select (arfcn_) {
    bsc/BSC_Tests.ttcn- case (tr_GsmBandArfcn((259..293), false, ?)) { band := "GSM450"; }
    bsc/BSC_Tests.ttcn- case (tr_GsmBandArfcn((306..340), false, ?)) { band := "GSM480"; }
    bsc/BSC_Tests.ttcn- case (tr_GsmBandArfcn((438..511), false, ?)) { band := "GSM750"; }
    bsc/BSC_Tests.ttcn- case (tr_GsmBandArfcn((128..251), false, ?)) { band := "GSM850"; }
    bsc/BSC_Tests.ttcn- case (tr_GsmBandArfcn((0..124), false, ?)) { band := "GSM900"; }
    ```
