SETRECUR: Command to set the recursion limit for the evaluation of nested variables within string variables.

syntax: SETRECUR=x, where x is a positive number for the recursion limit

To avoid infinite recursion which will stall the program, evaluation of variables names within string variables will by default be evaluated up to 26 levels deep. This means that you can nest variable names such as $B within another variable like $A and continue on with another variable name nested within $B and so on, up to 26 levels deep of nesting. The program will simply refuse to process expressions that nest variables more than the set recursion limit and display an error message. To increase or decrease the recursion limit, use the command "Set Recur=" with the desired limit placed after the equal sign.
