…state + capabilities
Adds the SHOW CPU DCL command (previously fell through to %DCL-W-IVKEYW).
Renders the authentic OpenVMS report from REAL system data:
- /SUMMARY (default): Multiprocessing ENABLED/DISABLED, PRIMARY CPU,
Active CPUs, Configured CPUs.
- /BRIEF: per-CPU "CPU nn is in RUN state".
- /FULL: per-CPU state + "Capabilities of this CPU:" (PRIMARY QUORUM RUN
for the primary, QUORUM RUN for secondaries) + the bound-process line.
Data is sourced from the running system, never fabricated (INV-6):
configured set from /sys/devices/system/cpu/present, active set from
/sys/devices/system/cpu/online (sysconf fallback), primary = lowest online
CPU (boot processor). Per-CPU state and capabilities are derived from those
real facts.
Honest omissions (HARD RULE 2 — omit rather than invent): the per-CPU
"Current Process:" line (OVMX executive tracks no per-CPU process binding),
the VECTOR capability, and the microcode "minimum multiprocessing revision
levels"/synchronization-image lines have no OVMX source, so they are omitted
rather than rendered as fabricated values. These need a future executive CPU
database (flagged in rd vms-a9e).
Report layout/wording is clean-room (Rule 8) from public OpenVMS docs only:
VSI OpenVMS Wiki SHOW CPU, the OpenVMS DCL Dictionary SHOW CPU entry, and the
marc.vos.net OpenVMS HELP mirror — cited in the source comment. No new
cross-image symbol or TU, so no native-link wiring changes.
Tests: tests/dcl/test_show_cpu.sh (summary: PRIMARY CPU + active/configured
sets from real data) and test_show_cpu_full.sh (per-CPU RUN state +
PRIMARY QUORUM RUN capabilities). Both fail on origin/main (IVKEYW) and pass
with this change; full-build dcl-integration suite green (ctest exit 0).

Summary
Implements the
SHOW CPUDCL command (rd vms-a9e). It was absent onorigin/mainand fell through to%DCL-W-IVKEYW. Now it renders the authentic OpenVMS SHOW CPU report from real system data.Forms
/ALL/SUMMARY):Multiprocessing is ENABLED/DISABLED,PRIMARY CPU,Active CPUs,Configured CPUs.CPU nn is in RUN state.Capabilities of this CPU:(PRIMARY QUORUM RUNfor the primary,QUORUM RUNfor secondaries) +Processes which can only execute on this CPU:.Real data (INV-6 — no fabrication)
/sys/devices/system/cpu/present/sys/devices/system/cpu/online(sysconf_SC_NPROCESSORS_CONF/_ONLNfallback)Honest omissions (omit rather than invent)
