I am writing a %do loop with decreasing iterative value. But this doesn't work. Can anyone help?
%do i=3 %to 1 by -1;
ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required. The condition was: 1 by -1
ERROR: The %TO value of the %DO I loop is invalid.
ERROR: The macro LOOP will stop executing.
