Thank you Team. I will write a UltraEdit macro to create the parameter concatenation directly in the .inp. Then open with eQuest to check for correctness.

Subject: RE: Another Keyword Expression question
I don’t think there is any way to reference U-NAMEs in expressions.
An alternative is to create the Global parameters by system number (in order that the systems are created), not by system name.
For example:
Your model has 10 systems. The first four systems that you define are packaged VAV systems named, in order of creation, “1stFlrN-PVAV”, “1stFlrS-PVAV”, “2ndFlrN-PVAV”, “2ndFlrS-PVAV”.
You want to assign unique COOLING-EIR to each system. You could use the following BDL input:
PARAMETER
"1st-system-CLG-EIR" = 0.310 ..
PARAMETER
"2nd-system-CLG-EIR" = 0.320 ..
PARAMETER
"3rd-system-CLG-EIR" = 0.330 ..
PARAMETER
"4th-system-CLG-EIR" = 0.340 ..
SET-DEFAULT FOR SYSTEM
TYPE = PVAVS
COOLING-EIR =
{switch #SV(#LS())
case 1 : #PA("1st-system-CLG-EIR") $ 1stFlrN-PVAV
case 2 : #PA("2nd-system-CLG-EIR") $ 1stFlrS-PVAV
case 3 : #PA("3rd-system-CLG-EIR") $ 2ndFlrN-PVAV
case 4 : #PA("4th-system-CLG-EIR") $ 2ndFlrS-PVAV
default : 0.360
endswitch}

Nick, Bill
I miss phrased the question. The expression should retrieve the system name, “SysName”, concatenate “-CLG-EIR” the set COOLING-EIR to “SysName-CLG-EIR” which is a parameter defined in Global parameters.
So the keyword expression would be in the COOLING-EIR Edit/View User Expression entry.

Request unclear… is this right?
1. You want an expression for a ZONE input to vary based on the string which is the name of the parent SYSTEM?
2. You further want a global parameter (#PA) defined as a string to be returned for insertion into said expression?
Maybe another line of context as to what you’re trying to achieve could help as well =).

I am looking for a way to retrieve the SYSTEM NAME from a child of system. For example:
COOLING-EIR = (#PA(“SysName-CLG-EIR”)
Where SysName-CLG-EIR is a parameter like “Parking Garage System-COP-EIR”
