====== Description ======
Mnemonic constants function as proxies for numeric values.  They can be used in place of numeric input for [[k|constant]] nodes and argument definitions.  A single mnemonic constant can be used in an unlimited number of places.  Its value is global to the knowledge base.

Values are assigned to mnemonic constants in the [[netweaver:windows:data list|data list editor]] on the "k" tab.

Common uses are:
  * To give self-evident meanings to a constant: MaxSpeed = 55
  * To make it easy to change values globally
  * To make it easy to edit controversial thresholds at the knowledge base level instead of buried where the constants are used.

Mnemonic constants are created simply by typing in a suitable name instead of a numeric value when editing constants or argument definitions.

====== Constraints ======
The value can be any numeric value or NULL (blank - no value). 

====== Calculus ======
The value is set in the [[netweaver:windows:data list|data list editor]].
