070B-GPRTE¶

MON 60 subfunction GPRTE = 70B = 0x38 = 56 decimal. NPL purpose (authoritative, 5P-P2-MON60.NPL): READ A PROCESS TABLE ENTRY FROM THE SYS.MON, server handler 5NOPAR.

All addresses OCTAL, ND-100 word addresses, BANK 1, base 0. Source: SINTRAN/ND500/nd-500-mon/nd-500-mon-j04.prog.asm

60B yaml client name = GPRTE. Three call sites: 073472, 074030, 110410.

Error path (callsite+1)	074031 `JPL I 51` -> routine 177327 = LEAVE-with-value (propagates error code)	PROVEN
Success path (callsite+2)	074032 (fall through) `LDA ,B -170`	PROVEN

Parameter block (PROVEN stores)¶

Slot	Store	Value
`,X 6` @073466/@074024/@110404	`STA ,X 6`	parameter 1 (site1 `&(B-166)`, site2 `&(B-172)`, site3 value from `LDA 162`)
`,X 7` @073471/@074027/@110407	`STA ,X 7`	parameter 2 (site1 `&(B-75)`, site2 `&(B-170)`, site3 `&(B-166)`)

Gateway convention (prog.md sec 4.4): LDX ,B -176 sets X = stack top; STx ,X 6/7/10 are MON 60 parameters 1/2/3.

What it does¶

Reads one ND-500 process-table entry from the system monitor.
Each of the three sites sets two parameters (,X 6 and ,X 7): a selector/index and a receive-buffer pointer into the local frame.
Sites 1 and 2 propagate a MON 60 error via LEAVE-with-value (177327); site 3 branches to a local error handler 110374. All three fall through on success.

Unknown / inferred¶

PROVEN: two parameters at ,X 6/,X 7 at each of the three sites (addresses cited above).
INFERRED (semantic): which of the two is the process index and which the receive buffer was not carved; per NPL the call reads a process-table entry.
PROVEN (role): 177327 = LEAVE-with-value (sites 1,2). 110374 (site 3) is a local error handler (target PROVEN, internals not carved).
INFERRED: READ A PROCESS TABLE ENTRY FROM THE SYS.MON from SUBFUNCTION-TABLE.md; thunk SAA 70 PROVEN.
