Package ELLI contains 2 self-evaluating symbols RAE and RCE. They are used in following function:

CONFIG

Takes zero or one arguments. With zero arguments it just returns the symbol representing the cofiguration. One argument that can be supplied must be one of the symbols RAE or RCE. The IrElliSoft configuration variable controls the formatting of the output .big files.

>(elli::config 'elli::rae)  
ELLI::RAE
 
>(elli::config elli::rce)  ; self-evaluating symbol also works
ELLI::RCE

INFO

Takes one argument that must be string. Sends the string to the main application window log text. Can be used for reporting progress of the Lisp script to the user. Returns the string.

>(elli::info "Hello, World!")
"Hello, World!"   ; this is now printed on the main window

APPEND-LABEL

Takes one argument that must be string, or NIL. Temporarily adds the string to the sample/experiment label. Empty string or NIL erases the temporary appendix. Is used in scripts performing measurements with/without compensator. Returns the full sample/experiment label with the appendix.

>(elli::append-label " with SiComp")
"YBCO film on LAO with SiComp"
 
>(elli::append-label NIL)
"YBCO film on LAO"
