On-call notes say use COND=EVEN on the notify step and COND=ONLY on the cleanup-after-abend step. I still mix them up when editing JCL at 2am.

Plain English cheat sheet? And do you still use COND or did everyone move to IF/THEN in JCL?

EVEN = run even if a prior step abended. ONLY = run only if a prior step abended.

We use IF/THEN for new jobs. COND stays in a pile of ancient procs nobody wants to touch.

Tape that EVEN/ONLY line above your desk. I still whisper it to myself during IPLs.
