    I want to run perl command with dynamic argument in SystemVerilog. And
    I use Cadence IUS583.

    When I try to pass a string to $system(), the ncvlog said "Using String
    without index is not supported in the given context."

    The code I write like below,
    string perl_cmd_str = "";

    $sformat(perl_cmd_str,"perl ./perl/ -a %0d -b 4",
    $display("string is %s\n", perl_cmd_str);

    $system (perl_cmd_str);

    Any suggestion on how to input string to $system()?

    $system is an old non-standard Verilog task. I wouldn't expect
    updating it to work with SystemVerilog strings to be a high priority.
    I would suggest using a wide vector buffer to hold your string value,
    the way such things have always been done in Verilog.
