Specials values not allowed in PGM arguments ?!

I am trying to do a CMD to change the owner of all objects in a lib, but when a 
call to DSPOBJD is done (using specials values like *all) 

DSPOBJD OBJ(&LIB/*ALL) OBJTYPE(&OBJTYPE) OUTPUT(*OUTFILE) 
OUTFILE(QTEMP/DSPOBJIDZZZ)

it returns a CPD0084, telling that the ´*ALL        ´ not valid for the 
parameter OBJTYPE (that was the value of &OBJTYPE var). I dont know but I 
assume that the OBJTYPE parameter of DSPOBJD is 7 chars lenght.

What can be wrong ?
I really dont know.
