Note that ${file.ext} does not include a leading dot.
${file.nr}
An automatic sequence number belonging to the current output file.
It is automatically incremented for each output file that gets created
within the same job.
It is possible to format the number using a pattern and locale. See
"Formatting date and number values " on page1346, below.
${file.pageCount}
This variable was introduced for use in Printer Definitions for
PostScript printers.
As it entails page buffering and could easily lead to Out of Memory
errors with big jobs, usage of this variable in an Output Preset or
in the Print Wizard is discouraged; it should be regarded as
deprecated.
Job
${job}
${job} is a shorthand for ${job.base}_${job.nr,0000}.${job.ext}. It
expands to a name based on the name of the applied Job Creation Preset
(or 'Untitled' if no Job Creation Preset was used). A four digit sequence
number is added at the end of the base name. The file extension is
determined by the selected output format.
The 0000 in ${job.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1346, below.
${job.base}
or
${job.name}
Returns the name of the applied Job Creation Preset without any extension.
Expands to Untitled if no Job Creation Preset was used.
${job.nr}
An automatic sequence number belonging to the current output file. It is
automatically incremented for each new output file that gets created. Note,
that multiple output files are created, for example, when output separation
has been selected for output creation.
