Try something like this:
Get_Token();
if(Token.Token_Id == COMMA_TOKEN)
{
SecondParam = (int)Parse_Float();
}
else
{
Unget_Token();
}
In other words, peek at the next token to see if it is a comma, in which
case another parameter has been specified. A more generalized version of
this could make a nice macro...
