### 5.2.6 export

`Syntax:`
  `export` name `;`
  `export` list_of_names `;`
`Purpose:`
  converts a local variable of a procedure to a global one, that is the identifier is not removed at the end of the procedure. However, the package the variable belongs to is not changed.
`Note:`
  Objects defined in a ring are not automatically exported when exporting the ring.
`Example:`

      proc p1
      {
        int i,j;
        export(i);
        intmat m;
        listvar();
        export(m);
      }
      p1();
      ==> // m                    [1]  intmat 1 x 1
      ==> // j                    [1]  int 0
      ==> // i                    [0]  int 0
      listvar();
      ==> // m                    [0]  intmat 1 x 1
      ==> // i                    [0]  int 0
