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.
