QWCORDFEAT, or more correctly QGPL/QWCORDFEAT, is a DTAARA which may exist on AS/400 model 720/730/740/7xx.
The then-new iSeries and AS/400e machines have an additional level called the "Interactive Feature". What was previously called the feature code is now referred to as the "Processor Feature". e.g. a 720-2062 (Model 720, Feature Code 2062) is now a 720-2062-1501 (Model 720, Processor Feature 2062, Interactive Feature 1501). 
It is not a base part of OS/400 but is enabled by PTFs [information unknown], and can be displayed using the command below.
