Hi,   I am trying to find out if there is a simple way to get the min or max of a group of macro variables containing numeric values. For example:   %let a = 5; %let b = 7; %let c = 6; %let d = 9;   Sometimes the value of one of these variables may change and I would like to always keep track of which has the maximum value, something like a macro version of min or max like %let maxval = %max(&a, &b, &c, &d);   These macro variable values contain the number of "value pairs" in different datasets, and by knowing the maximum number I can dynamically create enough columns for a combined report. Any suggestions would be helpful.    Thanks,   Bob ... View more
