@SysDatabase @FontDef problem

[flamasuta]

I don't know if it is possible at all but...

I'm trying to write a fax template with Lout.
I want to merge a data file (produced by a program) with the template 
to obtain a fax document in Postscript.
I have to manage several languages (english, italian, french and 
czech) and I would like to have only one template for all the 
languages.
To acheive this, I tried to define some macros according to the 
language defined in the data file but I get an error and I don't know 
what to do to bypass it.


command used:
lout fax_template.lt > fax.ps


output given by the command:
lout file "fax_template.lt":
   13,25: name of @Database file expected here
    25,1: fatal error: exiting now


Here is a light version of the data file:

========== begin ==========
macro @NX_language
{
Czech
}

macro @NX_logo
{
logo.ai
}


macro @NX_text
{
Some text in Czech...
}
==========  end  ==========


Here is a light version of my template file:

========== begin ==========
@Include { fax_setup.lt }
@Include { fax_data.lt }

macro @NX_font_definition
{
    @NX_language @Case
    {
        Czech @Yield { latin2 }
        else  @Yield { fontdefs }
    }
}

@SysDatabase @FontDef { @NX_font_definition }

macro @NX_font_encoding
{
    @NX_language @Case
    {
        Czech @Yield { CE }
        else  @Yield {}
    }
}

@Document
    @InitialLanguage { @NX_language }
    @InitialFont { address@hidden Bold 11p }
    @PageHeaders { None }
//

@Text @Begin
@Centre 1.6c @High -90d @Rotate @Scale 90d @Rotate @IncludeGraphic { 
@NX_logo }
@LP
{ lines 1.2fx } @Break {
@NX_text
}
@LP
@End @Text
==========  end  ==========
