164B UNDOC¶
MON 60 subfunction 164B (octal) = 0x74 = 116 dec.
Undocumented (server dispatch 5NOPAR). There is no FUNCTION= comment for code
164 in 5P-P2-MON60.NPL; the SINTRAN dispatch for it is the generic 5NOPAR path.
The subfunction purpose cannot be recovered from this ND-100 binary alone; only what
the caller does is carved here.
All addresses are OCTAL ND-100 word addresses, BANK 1, base 0.

Thunk 147014 = SAA 164 ; JMP I 1 ; 146244 (gateway). Confirmed verbatim in the .asm.
Handler location(s)¶
| Call site | Enclosing ENTER-routine | Framesize | Error path (callsite+1) | Success path (callsite+2) |
|---|---|---|---|---|
| 141310 | 141305 | 000000 | 141311 -> ptr 141315 = 177327 (LEAVE error) | 141312 -> ptr 141316 = 177335 (LEAVE-SKIP) |
Every call site resolves as JPL I <disp> -> EA=P+disp -> bank1[EA] = pointer word
= thunk 147014 (PROVEN by resolving the pointer word).
Parameter block filled before the call¶
Call site 141310 (in 141305):
- NONE. Parameterless wrapper; no 'STA ,X n' between ENTER and the call. PROVEN.
The block base is X := ,B -176 (stack top = base of the gateway frame); slot ,X n
becomes MON 60 parameter n-5 (PROVEN convention, prog.md sec 4.4).
What the caller does¶
Parameterless wrapper (0 locals): ENTER, issue subfunction, LEAVE. 141313-141316 is the pointer pool (177300, 147014, 177327, 177335).
Unknown / inferred¶
- UNKNOWN: the subfunction purpose (no FUNCTION= comment; generic 5NOPAR).
