ACTIV (ACTIVATE STOPPED PROCESS)

MON 60 subfunction ACTIV = 136B (octal) = 0x5E = 94 decimal. NPL purpose (authoritative, 5P-P2-MON60.NPL, via SINTRAN/ND500/nd-500-mon/mon60-callers/SUBFUNCTION-TABLE.md): ACTIVATE STOPPED PROCESS, server handler IPRACTIVE.

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

Handler location

Item	Value	Status
Enclosing ENTER-routine	002662 (framesize 000331) - the command interpreter	PROVEN
MON 60 call site	010610 JPL I 22 -> ptr 010632, bank1[010632]=146731 = thunk SAA 136	PROVEN
Error path	010611 (callsite+1) -> 010574 (local error handler for this case)	PROVEN
Success path	010612 (callsite+2) -> 010613 (command loop area)	PROVEN

Thunk verification (PROVEN, read from bytes)

146731 170536 SAA 136 ; 146732 125001 JMP I 1 ; 146733 146244 (gateway).

MON 60 subfunction used

Subfn	Octal / Hex / Dec	Thunk	Parameter-block layout	Skip/Error
ACTIV	136B / 0x5E / 94	146731	,X 6 = the 3-word F descriptor from B-113 = the process/domain name	err=010611->010574; ok=010612->010613

Only slot 6 is stored (010607 STF ,X 6, 3 words).

What it does

1. Loads the process/domain-name descriptor (F, 3 words) from B-113. (010605)
2. Places it in gateway param slot 1 and issues MON 60 ACTIV. (010606-010610)
3. On error -> the case's local error handler 010574; on success -> command loop 010613.

The local error handler at 010574 itself issues a secondary MON 60 (at 010601, ptr 010630) as part of its cleanup - a different subfunction, not this call.

Unknown / inferred

• PROVEN: subfunction identity, thunk bytes, the single 3-word param store, and the error/success targets.
• PROVEN: the parameter is a 3-word F descriptor (LDF/STF) = the process/ domain name. Server handler IPRACTIVE activates the stopped process.
