+/**
+  @file
+  @brief Apply leading blanks to align numbers vertically in a char variable
+  @details This is particularly useful when storing numbers (as character) that
+  need to be sorted.
+
+  It works by splitting the number left and right of the decimal place, and
+  aligning it accordingly.  A temporary variable is created as part of this
+  process (which is automatically dropped)
+
+  The macro can be used only in data step, eg as follows:
+
+      data _null_;
+        length myvar $50;
+        do i=1 to 1000 by 50;
+          if mod(i,2)=0 then j=ranuni(0)*i*100;
+          else j=i*100;
+
+          %mp_aligndecimal(myvar,width=7)
+
+          leading_spaces=length(myvar)-length(cats(myvar));
+          putlog +leading_spaces myvar;
+        end;
+      run;
+
+  The generated code will look something like this:
+
+      length aligndp4e49996 $7;
+      if index(myvar,'.') then do;
+        aligndp4e49996=cats(scan(myvar,1,'.'));
+        aligndp4e49996=right(aligndp4e49996);
+        myvar=aligndp4e49996!!'.'!!cats(scan(myvar,2,'.'));
+      end;
+      else do;
+        aligndp4e49996=myvar;
+        aligndp4e49996=right(aligndp4e49996);
+        myvar=aligndp4e49996;
+      end;
