This case-sensitive code system http://hl7.org/fhir/variable-handling defines the following codes:

CodeDisplayDefinitionCopy
continuous continuous variable A continuous variable is one for which, within the limits the variable ranges, any value is possible (from STATO http://purl.obolibrary.org/obo/STATO_0000251). btn btn

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
