1. Adding built-in routines to the euphoria interpretor

I'm trying to add some built-in routines to the eu interpretor. When I execute a
test program that calls the function "fiKernelInfo", it's telling me "unknown
opcode: 182".

In keylist.e I added some entries:

{"fiCallProc", SC_PREDEF, PROC, FI_CALL_PROC, 3, E_PURE},
{"fiCallFunc", SC_PREDEF, FUNC, FI_CALL_FUNC, 3, E_PURE},
{"fiOpenSession", SC_PREDEF, FUNC, FI_OPEN_SESSION, 1, E_PURE},
{"fiCloseSession", SC_PREDEF, PROC, FI_CLOSE_SESSION, 1, E_PURE},
{"fiKernelInfo", SC_PREDEF, FUNC, FI_KERNEL_INFO, 0, E_PURE}

rywilly i also added entries in opnames.e:

"FI_CALL_PROC",
"FI_CALL_FUNC",
"FI_OPEN_SESSION",
"FI_CLOSE_SESSION",
"FI_KERNEL_INFO"    --182

and in reswords.e

FI_CALL_PROC = 178,
FI_CALL_FUNC = 179,
FI_OPEN_SESSION = 180,
FI_CLOSE_SESSION = 181,
FI_KERNEL_INFO = 182,
MAX_OPCODE = 182

and added procedures in execute.e:

procedure opFI_CALL_PROC()
    a = Code[pc+1]
    b = Code[pc+2]
    c = Code[pc+3]
    fiCallProc(val[a], val[b], val[c])
    pc += 4
end procedure

procedure opFI_CALL_FUNC()
    a = Code[pc+1]
    b = Code[pc+2]
    c = Code[pc+3]
    target = Code[pc+4]
    val[target] = fiCallFunc(val[a], val[b], val[c])
    pc += 5
end procedure

procedure opFI_OPEN_SESSION()
    a = Code[pc+1]
    target = Code[pc+2]
    val[target] = fiOpenSession(val[a])
    pc += 3
end procedure

procedure opFI_CLOSE_SESSION()
    a = Code[pc+1]
    b = Code[pc+2]
    fiCloseSession(val[a])
    pc += 3
end procedure

procedure opFI_KERNEL_INFO()
    target = Code[pc+1]
    val[target] = fiKernelInfo()
    pc += 2
end procedure

When i call the fiKernelInfo() function in my test app, it says op code 182 is
unknown. So, it's seems to be partially working, but i'm missing something
somewhere. Does anyone know what else I need to do?

It looks like you forgot to update emit_op() in emit.e.
