Using @ to Access Data Fields in MEDITECH NPR
Consider the RAD.ORD.main segment.
main[urn]
$(R)RO[ro]
urn
arrive.time $(R)RO[ro]EX|11
RAD.ORD.urn is a subscript, you can access its value in your MEDITECH NPR report referring to it as @urn or urn. RAD.ORD.arrive.time does not translate to a local variable. This value requires a subscript to access the data. If you leave the @ symbol off of arrive.time you'll get this error: 
To get MEDITECH NPR to translate to the correct object code, you want to reference this field as @arrive.time.
