[Equest-users] setting daylight via global parameter

[Kevin Madison]

...
then #si("YES","SPACE","DAYLIGHTING")
else #si("NO","SPACE","DAYLIGHTING")
endif

... anytime you are trying to set a keyword with a symbolic data type, 
you must use the SymbolIndex() or #si() function. Symbolic keywords are 
those that take text inputs, either as a user defined command such as a 
schedule (e.g. SPACE:LIGHTING-SCHEDUL) or a BDL pre-defined symbol (e.g. 
SPACE:DAYLIGHTING or SYSTEM:OA-CONTROL)

You also have to make sure you are using the proper DOE-2 symbol value, 
not the eQUEST detailed interface value. To identify the correct DOE-2 
symbol value you can usually right click and look at the DOE-2 item help 
for that keyword and it will show you the valid inputs. Or, look at the 
.inp file and see what actually shows up for the input to a particular 
symbolic keyword.

Have fun.
