Abbreviating Keywords

Like commands, nearly all keywords have abbreviations. You may enter keywords spelled exactly as they are shown, or you may use an acceptable abbreviation. An acceptable abbreviation is as much of the keyword as is necessary to distinguish it from the other keywords of the command or subcommand. (If you supply an abbreviation which is not specific enough, the system will prompt you. An exception is the TSO/E HELP command that requires you to enter an operand unambiguously for proper results.)

The LISTBC command, which is used to display messages, has four keywords:

MAIL
NOMAIL
NOTICES
NONOTICES

The abbreviations are:

M for MAIL (also MA and MAI)
NOM for NOMAIL (also NOMA and NOMAI)
NOT for NOTICES (also NOTI, NOTIC, and NOTICE)
NON for NONOTICES (also NONO, NONOT, NONOTI, NONOTIC,
and NONOTICE)

Example
To request a listing of the broadcast data set without mail intended for you, you can type the abbreviated version of LISTBC NOMAIL after the READY mode message: `LISTB NOM`
