Efficiently applying an FE function to one ADO at a time
In this article I want to discuss a pattern of combining ac_evalform and runparallel that can both simplify the implementation as well as allow increased performance by parallel processing.

Share the load with runparallel
There is a very useful script called runparallel which allows you to distribute input coming from STDIN to multiple parallel incarnations of a process.

Getting static attribute values with get_attributes
In order to get the values of a few static attributes for a given set of ADOs on the command line or as part of a shell script you can use get_attributes.

Retrieving ADO list contents with listado
To retrieve the contents of an ADO list from the command line or from within a shell script, you can use listado.

A touch of functional programming with map()
Formula Engine - like many other programming languages - offers a map function.

Sublists with elt()
If you want to create sublists of lists in Formula Engine, you can use the function elt.

Writing to files with text_write()
The Formula Engine function text_write allows you to write to text files.

Do not delete datafile attributes
If you are thinking of deleting a datafile attribute from Asset Control, here are a few things to consider:

Checking server threads with qsti and usti
Two fundamental commands you will use to see what the query and update servers are currently doing in an Asset Control installation are:

Find datafile paths with bp
You may know that the actual datafiles holding timeseries on the filesystem are organized within a multi-layered directory structure so that they are distributed across many directories rather than kept in a single directory.
