Example: lr_paramarr_random

This example shows how to get a random value from a parameter array.

char * FlightVal;
web_reg_save_param("outFlightVal", 
    "LB=outboundFlight value=", "RB=>", 
    "ORD=ALL", 
    "SaveLen=18", 
    LAST ); 
web_submit_form("reservations.pl", 
    "Snapshot=t4.inf", 
    ITEMDATA, 
    "Name=depart", "Value=London", ENDITEM, 
    "Name=departDate", "Value=11/20/2003", ENDITEM, 
    "Name=arrive", "Value=New York", ENDITEM, 
    "Name=returnDate", "Value=11/21/2003", ENDITEM, 
    "Name=numPassengers", "Value=1", ENDITEM, 
    "Name=roundtrip", "Value=<OFF>", ENDITEM, 
    "Name=seatPref", "Value=None", ENDITEM, 
    "Name=seatType", "Value=Coach", ENDITEM, 
    "Name=findFlights.x", "Value=83", ENDITEM, 
    "Name=findFlights.y", "Value=16", ENDITEM, 
    LAST ); 
The result of the web_reg_save_param having been called before the web_submit_form is: 
Notify: Saving Parameter "outFlightVal_1 = 230;378;11/20/2003"
Notify: Saving Parameter "outFlightVal_2 = 231;337;11/20/2003"
Notify: Saving Parameter "outFlightVal_3 = 232;357;11/20/2003"
Notify: Saving Parameter "outFlightVal_4 = 233;309;11/20/2003"
Notify: Saving Parameter "outFlightVal_count = 4"
FlightVal = lr_paramarr_random("outFlightVal");
