Description: GNU dc arbitrary precision reverse-polish calculator
 GNU dc is a reverse-polish desk calculator which supports unlimited
 precision arithmetic.  It also allows you to define and call macros.
 .
 A reverse-polish calculator stores numbers on a stack. Entering a number
 pushes it on the stack.  Arithmetic operations pop arguments off the
 stack and push the results.

a=42
b=11+a
