‘Hello World’

Perhaps a more flavorful example would take a list of strings, sort them into order, and then return that as a result instead.

<PRE>

// First declare a dataset with one column containing a list of strings

// Datasets can also be binary, csv, xml or externally defined structures

D := DATASET([{'ECL'},{'Declarative'},{'Data'},{'Centric'},{'Programming'},{'Language'}],{STRING Value;});

SD := SORT(D,Value); <br>

output(SD)

</PRE>

The statements containing a := are defined in ECL as attribute definitions. They do not denote an action; rather a definition of a term. Thus, logically, an ECL program can be read: “bottom to top”
