DEFM

MON 60 subfunction 040B (octal) = 0x20 = 32 decimal. NPL purpose (authoritative, 5P-P2-MON60.NPL, via SUBFUNCTION-TABLE.md): (define memory configuration), server handler 5NOPAR. Client name (yaml 60B_N500M.yaml): DEFM, "Define memory configuration", params <start page> <no. of memory parts> <part array>.

Operator-command note: INDEX.md section 2.1 maps this call site to the DEFINE-MEMORY-CONFIGURATION command (PROVEN there). Named here by subfunction.

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

Skip / error handling

• ERROR (callsite+1): 135362 JPL -37 -> 135323 (local error-handler code).
• SUCCESS (callsite+2): 135363 JPL I 2 -> ptr 135365 = 177335 = LEAVE-SKIP.

Note: 135346 JMP 13 jumps over the routine's inline pointer pool (135347-135360) to reach the call at 135361.

Unknown / inferred

• INFERRED (semantic): parameter labels follow the yaml order; stores/offsets PROVEN.
• INFERRED (role): 135323 is the routine's local error handler; not traced.
