CompoundExpression

expr1;expr2;…

evaluates the expri in turn, giving the last one as the result.

Details

  • CompoundExpression evaluates its arguments in a sequence corresponding to the control flow.
  • The returned value can be the result of Return[expr].
  • The evaluation of the expri can be affected by Return, Throw, and Goto.
  • expr1;expr2; returns value Null. If it is given as input, the resulting output will not be printed. Out[n] will nevertheless be assigned to be the value of expr2.
