Predefined user variables: Arithmetic parameters (R)

Function
Arithmetic parameters or R-parameters are predefined user variables with the designation R,
defined as an array of the REAL data type. For historical reasons, notation both with array
index, e.g. R[10], and without array index, e.g. R10, is permitted for R-parameters.
When using synchronized actions, the $ sign must be included as a prefix, e.g. $R10.
Syntax
When used as a preprocessing variable:
R<n>
R[<expression>]
When used as a main run variable:
$R<n>
$R[<expression>]
