<font face="Courier New">Dear All,<br>
<br>
I'm trying to use the error messages available at <a
class="moz-txt-link-freetext"
href="https://help.scilab.org/docs/6.0.2/en_US/error_table.html"
moz-do-not-send="true">https://help.scilab.org/docs/6.0.2/en_US/error_table.html</a><br>
<br>
However, I cannot find one that describes precisely what is
wrong.<br>
<br>
My argument is any scalar, vector, matrix or N-D array of real
or complex numbers.<br>
<br>
If I use<br>
<br>
"%s: Argument #%d: Decimal or complex number expected.\n"<br>
<br>
it may convey the idea that only scalars are admissible. I think
the word "number" jeopardizes the message. It would be better if
the word "type" were clearly mentioned, for instance "Wrong
input type: %d expected.\n"<br>
</font></blockquote>
<p><br>
</p>
<p>Yes, but to me, "input" is useless, since only input types are
testable. In addition, the argument's number must appear. So yes,
something like</p>
<p><font face="Courier New">"%s: Argument #%d: Decimal or complex
type expected.\n"<br>
<br>
</font><tt>would be better</tt><tt>. A still more open message is
possible and already listed:</tt></p>

<br>
"%s: Argument #%d: Hypermatrix expected.\n"<br>

it may be interpreted as if, for instance, a polynomial
hypermatrix would be acceptable.<br>
</font></blockquote>
<p>Yes, or of any other type, since this message only informs about
the size / format, not about the data type. It is is in the same
messages section "Checking container's dimension and sizes" than
other messages about the shape / array size. </p>

<p>But impossible. An error message is not aimed to replace the help
page. There may be many possibilities. <br>
If in the function that you write you want to display the
documented list of available syntaxes for this function, just
before the proper error message, then <tt><a
