I am worried SASM has not been supported in any version of MPLAB. The debugger used in the Picbook for 18F is not able to work together with MPLAB. You have to assemble your hex file by SASM (or any other assembler like MPASMWIN from Microchip) and debug your code using some terminal and directives the debugger is able to understand. MPLAB communicates with its debugger by the very different way.
