<td class="print-category">Description</td>
<td colspan="5" class="print">During porting code from a different
TTCN-3 tool to our tool, we encountered an interesting problem. The
problem is related to the following code:<br />
<br />
type record MyRecord<br />
{<br />
  charstring field1,<br />
  charstring field2,<br />
  charstring field3<br />
}<br />
...<br />
var MyRecord v_MyList1;<br />
var MyRecord v_MyList2;<br />
v_MyList1 := {value1”, “value2”, “value3” };<br />
v_MyList2.field2 := “newvalue”; // leaving field1 and field3
uninitialized<br />
<br />
v_MyList1 := v_MyList2;<br />
<br />
In our tool, the value of v_MyList1 after the last assignment is
{&lt;uninitialized&gt;, “newvalue”, &lt;uninitialized&gt;}, while in the
other tool it is {“value1”, “newvalue”, “value3” }.<br />
<br />
Our position is that only general assignment rules apply to the last
assignment, thus the whole record value is assigned to the v_MyList1
variable completely ovewriting its previous content.<br />
<br />
The specification does contain rules that allow the original values to
be kept after an assignment, but these rules are related to specific
value notations occuring on the RHS: assignment notation and list
notation (specified in 6.2).<br />
<br />
In order to prevent this kind of different interpretations, we would
welcome if the next edition of the TTCN-3 standard contained either a
note or an explicit rule mentioning that the whole value is assigned in
this case including uninitialized fields (i.e. all fields of the
original value get overwritten).</td>
