   '-NOBcx-'   

When the instruction displayed on the main panel is a BC or BCR, BCX shows an extended branch mnemonic instead of the CC mask when disassembling the instruction. Mnemonics used are those for use after compare instructions. This option has no effect on branch relative instructions.

NOBCX does not show BC and BCR instructions as their extended mnemonics, but shows the CC mask instead.
