Hi all,
    How are u? hope all is allright!

    well... just a small questions about if()!

    does djgpp continue to evaluate an expression of
an if statement even if the result is readily
available?
    i.e.  consider this...
    if (0&&dummy1)
       statement here;
     
    well it evaluate dummy1??

    if it doesnot, can i count on it? there aren't any
exceptions??

    i need it mainly for this example!
    if(structptr&&structptr->value>20)
        statement;
  
    i.e. if structptr is not null and there is a
condition on a certain field!

    if djgpp evaluates the whole expression and
structptr is NULL, it will cause a GPF!!!

   that's why i need it!! :)

thanx in advance! c u soon!

Urs forever,
   Mohamed El Dawy
