Like in Verilog, VERA supports left and right shift operators as shown below.

• The left operand is shifted by the number of bit positions given by the right operand.
• The vacated bit positions are filled with zeroes.

  1 program shift {
  2   // Left Shift
  3   printf (" 4'b1001 << 1 = %b\n", (4'b1001 << 1));
  4   printf (" 4'b10x1 << 1 = %b\n", (4'b10x1 << 1));
  5   printf (" 4'b10z1 << 1 = %b\n", (4'b10z1 << 1));
  6   // Right Shift
  7   printf (" 4'b1001 >> 1 = %b\n", (4'b1001 >> 1));
  8   printf (" 4'b10x1 >> 1 = %b\n", (4'b10x1 >> 1));
  9   printf (" 4'b10z1 >> 1 = %b\n", (4'b10z1 >> 1));
 10 }

  4'b1001 << 1 = 0010
  4'b10x1 << 1 = 0x10
  4'b10z1 << 1 = 0z10
  4'b1001 >> 1 = 0100
  4'b10x1 >> 1 = 010x
  4'b10z1 >> 1 = 010z
