I didn't mean to be rude to anyone. It's just a very packed afternoon in a very bad day. Sorry if anyone felt offended.

I have here a little piece of my code which illustrates the problem. I probably forgot to say that f(z,r) will be used as a dummy function, which will be specified later in the program... > restart > assume(r, real) > assume(z, real) assume(delta, real) > F := f(r, z) >assume(F, real) >G := F exp(-I delta z) > print(); f(r, z) exp(-I delta z) >conjugate(G) > print(); _______________________ f(r, z) exp(-I delta z) >

I m doing some symbolic calculation, so I have no explicit form for f(r,z), this means that I have no way of telling Maple that I want F:=f(r,z) to be real... As a matter of fact, in the following step I'm multiplying F:=f(r,z) by a complex exponential: G:=F*exp(-I*delta*x) then, I take the complex conjugate. At this point the program takes the complex conjugate of F, even if F should be real...(unless there is a way to spevify the f(x,y) must be REAL)!!! THANK YOU FOR REPLYING!!!!!

PLEASE, IM REALLY STUCK WITH THIS..I KNOW IT'S STUPID BUT... YOUR HELP HERE IS REALLY NEEDED AND APPRECIATED ..PLEASE DO NOT IGNORE THE POST ABOVE...!!! HAVE PITY!!!
