RELFUN Toplevel

In FLIP-extended RELFUN, three different toplevels are present: the interpreter, the emulator, and the LL toplevel. They are entered with inter, emul, and ll, respectively.

For the commands available at the interpreter and emulator toplevels, refer to the RELFUN documentation [\protect\citeauthoryearBoley et al.1991] and [\protect\citeauthoryearBoley et al.1993].

At the LL toplevel, the following commands are available:

• load : load and compile an LL file (if no extension is present, ``.lisp'' is assumed)
• spy: switch to spy mode (the executed machine code is displayed)
• nospy: finish spy mode
• asm mod lluser: show contents of LL name space
• asm l : display a memory area (addresses - )
