[string] check for arguments function

Expand/// args( str, substr, pos );
//
//  Checks the given string for a substring at the given position.
//  Example: if (args(str, "str", 1)) show_message("yes");
//
//      str            the string to check in, STRING
//      substr       the substring to check in the string, STRING
//      pos           the position to check at in the string, INT
//
//  What differs this script from the built-in "string_pos" function,
//  is that this function can check for a string at any position and not just the first occurrence.
//

{
    var eStr = string( argument1 );                // string to check in
    var eStart = real( argument2 );                // position to check at
    var eCheck = string_lower( argument0 );  // lowercase in string
    
    var ii = 0;  // temp variable to check if we should return true
    for ( var i = 0; i < string_length( eStr ); i++ ) {
      if ( string_char_at( eStr, 1 + i ) == string_char_at( eCheck, eStart + i ) )  // check if characters match
        ii++;  // add to temp variable
    }
    
    if ( ii = string_length( eStr ) ) return true;  // return true if temp variable is equal to string length
    return false;  // or return false
}
