    "inParam" ); 
iRetVal = web_reg_save_param_ex( 
    "ParamName=newParam", 
    "LB/IC=ll",

    "Action=http://localhost/cgi-bin/echo.asp", 
    "Method=POST", 
    "TargetFrame=",

示例2：正則表示式的運用示例

lr_save_string( "LL111 Value1 111RR\r\n" 
    "LL222 Value2 222RR\r\n" 
    "LL333 Value3 333RR\r\n" 
    "LL444 Value4 444RR\r\n", 
    "inParam" ); 
web_reg_save_param_ex( 
    "paramName=ex_example0", 
    "LB/RE=LL111",        
    "RB/RE=222RR",         
    LAST); 
web_reg_save_param_ex( 
    "paramName=ex_example1", 
    "LB/RE=LL[0-9]*",    // "LL" followed by zero or more symbols in range [0-9] 
    "RB/RE=.RR",        // Any symbol followed by "RR" 
    LAST); 
web_reg_save_param_ex( 
    "paramName=ex_example2", 
    "LB/RE=LL[0-9]+",    // "LL" followed by at least one symbol in range [0-9] 
    "RB/RE=.2RR",        // Any symbol followed by "2RR" 
    LAST); 
web_reg_save_param_ex( 
    "paramName=ex_example3", 
    "LB/RE=LL(33)+",    // "LL" followed by at least one instance of string "33" 
    "RB/RE=[3a]RR",        // Exactly one symbol ('3' or 'a') followed by "RR" 
    LAST); 
web_reg_save_param_ex( 
    "paramName=ex_example4", 
    // "LL" or "123" folowed by at least one instance 
    // of string containing symbols [4-9] and space 
    "LB/RE=((LL)|(123))[4-9 ]+", 
    // At least one instance of string containing symbols [4-9] 
    // and space followed by "RR" 
    "RB/RE=[4-9 ]+RR", 
    LAST);
