It is possible to format the number using a pattern and locale. See
"Formatting date and number values " on page872, below.
${template.ext}
The extension that corresponds to the chosen output technology.
For example, for PDF output, ${template.ext} would be PDF, for
PostScript output, ${template.ext} would return PS
Note, that ${template.ext} does not include a leading dot.
The File object
${file}
${file} is basically a short hand for ${file.base}_
${file.nr,0000}.${file.ext} where 0000 in ${file.nr,0000} is a
format pattern that takes care of formatting the number with at least four
digits including leading zero's. See "Formatting date and number
values " on page872, below.
Server context:
On the Server, ${file} expands to a file name based on the job name. A
four digit sequence number is added at the end of the basename. The
suffix (the extension) is defined by the selected output technology.
Example
If the job name is my-invoices-reprint and is printed to PDF, then
${file} expands to my-invoices-reprint_0001.pdf
Designer context:
In the Designer, ${file} returns a generated name based on the
current template name. A four digit sequence number is added at the
end of the basename. The suffix is defined by the selected output
technology.
Example
If the template file is my-invoices.OL-template and is printed to
PostScript, then ${file} expands to my-invoices_0001.ps
${file.base}
The name of the template without dot extension (designer context) or
the name of the job without dot extenstion (server context)
