Isaac, I'll see what I can do with that. The problem is that the
SMEL-parser reads SMEL-code character per character. And to implement the
heredoc-construction the parser will have to read several characters ahead
to know where the end is. Heredoc is easy to implement on a line-based
system (which reads lines), but SMEL is a character-based system. And when
you say <<<END, the parser will have to read the END-string. Where does
the END-string end and the actual text-data begin?

I may have found a way to implement a construction that functions like
the heredoc-construction. It begins with >ID and ends with ID: ID is an
identifier that you can chose yourself (can ofcourse not occur in the
text-data).
Example:
app(id=!MyApp start=!MyWindow)
{
window(id=!MyWindow size=[300,200] caption='My Window')
{
button(id=!MyButton1 location=[10,10] size=[50,20] caption='Close 1');
button(id=!MyButton2 location=[70,10] size=[50,20] caption='Close 2');
event(for=!MyWindow type=!OnClosing id=!MyWindow_Close);
event(for=[!MyButton1,!MyButton2] type=!OnClick id=!MyButtonX_Click);
}
procedure(id=!MyButtonX_Click params='object sender')
{ > PROCEDURE_MYBUTTONX_CLICK
if sender = MyButton1 then
wPuts(MyWindow, "Clicked MyButton1, closing...")
elsif sender = MyButton2 then
wPuts(MyWindow, "Clicked MyButton2, closing...")
end if
closeWindow(MyWindow)
PROCEDURE_MYBUTTONX_CLICK
}
procedure(id=!MyWindow_Close params='object sender')
{ > PROCEDURE_MYWINDOW_CLOSE
wPuts(MyWindow, "You can't see this because the window is closing.")
PROCEDURE_MYWINDOW_CLOSE
}
}

I have added the HereDocText-construction to SMEL. To implement it, you
have to use a $, followed by an identifier (starts with a letter, and only
contains letters, numbers, _ and -).
In the following example, a HereDocText-value with delimiter END_OF_CODE
is used:
<smel version='1.1'>
app(!MyApplication)
{
function(!MyFunction, params='object a, sequence b')
{
"-- Some regular double quote-delimited text"
'-- Some regular single quote-delimited text and ' $ END_OF_CODE
if sequence(a) then
return a
else
return b
end if END_OF_CODE
} /* end of function */
} /* end of app */
