[Bldg-sim] DOE2 User Input Expressions

[Scott Criswell]

Brian's suggestion is a good one, but requires the use of global parameters.

This correction however will fit directly into your particular project:

if (#L("LIGHTING-SCHEDUL",0) ==
    #SI("Classroom InstLt Sch","SPACE","LIGHTING-SCHEDUL"))
then  1.2
else  0
endif

Things to note:
- DOE-2 keyword names are limited to 16 characters, hence the use of 
"LIGHTING-SCHEDUL" in place of your "LIGHTING-SCHEDULE"
- LIGHTING-SCHEDUL is actually an array of 5 individual schedule 
assignments, so we specify the optional second #L() argument of "0" 
indicating that we are interested in retrieving the first (0-based, not 
1-based) element in the list (which is the default).
- Use of the #SI() function so that we are comparing a symbol table 
index to another symbol table index.
