I am trying to put a subroutine at a fixed address (I want it to remain fixed after the code is rebuilt and other modules are changed). First I linked my code and obtained its absolute linked address (assigned by the linker). Then I used the _at_ (0x07A) command in the C source file. I got a FIXUP error when I linked. When I did the same thing using the linker SE command, I didn't get any errors. I really wanted to cast the addresses in the source C code file using the _at_ command but I am having problems.... Any thoughts... Thanks, Jim
