The /TEST keyword to DEFSYSV allows you to set default values for system variables; that is, if the value is not already set by an upstream process, DEFSYSV will set it. This is what the documentation says:
https://harrisgeospatial.com/docs/DEFSYSV.html
"TEST: Set this keyword to create a new system variable only if one does not currently exist."

But when we try to do this:

IDL> defsysv,'!VAR',0,/test
% Keyword TEST not allowed in call to: DEFSYSV

IOID (Implemented Only In Documentation)?
