Hi Corona,

I need another small improvement in the code

Say the input file is the one below. I need to replace 1st P0 with M0 and second with 00 if and only if the value of port is 1 on both V{}

Say the input file is the one below. I need to replace 1st P0 with M0 and second with 00 if and only if the value of port3 is not 1 on both V{}

Input file

Code:
V { 
    port1       = P;
    port2       = 0;
    shift_port  = P0; 
    port3       = 1; /* port 3 is 1 . So dont replace this even if next shift port is P0 */
    reset       = 1;
   }
  W wf_cyc;
  V { 
    port1       = P;
    port2       = 0;
    shift_port  = P0; /* port 3 is 0 and current shift_port is P0. If port 3 is 0 in next v{} and shift_port is P0 then replace this with M0 and next shift port with 00 */
    port3       = 0;
    reset       = 1;
   }

 W wf_cyc;
  V { 
    port1       = P;
    port2       = 0;
    shift_port  = P0;
    port3       = 0;
    reset       = 1;
   }

  Macro "Inputs" { 
    test_ip =

  }
