DALOPTCD specifies optional services to be performed. When you
code this key, # and LEN must be one, and PARM contains one of the
following values:
- X'01'
- Relative block addressing (R), or to select character arrangement tables for the 3800 printer (J)
- X'02'
- User totaling facility (T)
- X'04'
- Reduced tape error recovery or direct DASD search (Z)
- X'08'
- Direct addressing (A), or translation of ASCII to or from EBCDIC (Q)
- X'10'
- Feedback (F), or hopper-empty exit (H), or online correction for optical readers (O)
- X'40'
- Disregarding end-of-file recognition for tape (B), or allowance of data checks caused by an invalid character.
- X'80'
- Write validity check.
Note: When you are specifying more than one OPTCD value, PARM contains
the sum of the values.
For more information regarding the OPTCD specification key, see z/OS DFSMS Macro Instructions for Data Sets.
Example: To specify OPTCD value B, code: KEY # LEN PARM
