Variable Names with Subcripts?

Questions
1

If I have a variable, I’m trying to reference the variable in CL & in the graph itself & in the graph, to make it appear on a label. I know sometimes we have to use underscore and sometimes {}, but can’t figure out the combo. Thanks!

variable: a
CL:
Graph:
Label:

variable: a_b
CL:
Graph:
Label:

variable: a_bcde
CL:
Graph:
Label:

variable: a
CL: Try something like number("a"): .....
Graph: No special formatting needed
Label: ${a}

variable: a_b
CL: number("a_b"): .....
Graph: Type a_b
Label: ${a_b}

variable: a_bcde
CL: number("a_{bcde}"): .....
Graph: Type a_bcde
Label: ${a_bcde} or ${a_{bcde}} should work

The rule I always use is that if a subscript is needed, use an underscore. If there is more than one letter needed for the subscript, then use braces around everything that should be in the subscript.
