Hi,
      I am looking for a macro that can work with both VAR and VAL.
More examples of usages are showed below:

  %let x1 = 12.3;
   %let x2 = 23;
   %let x3 = 45.3;

   %picture(&x1 &x2 &x3, fmt= Output three values: xx.x xx, and  xx.x)
== >  Output three values: 12.3 23, and 45.3

   %picture(&x1 &x2 &x3, fmt= Output estimated value and CI: xx.x
[xx,xx.x] ) == >  Output estimated value and CI: 12.3 [23,45.3]

   The output formats for the macro are various and unlimited.

    Either data step or pure macro code can  be used for the
implementation.

    I am not against using REGEX (regular expression functions) to
parsing the &fmt if there is no other better solution with basic macro
string functions.
