File preferences
Description
After the user preferences window has been shown,
the file preferences window appears. This window contains settings which apply
to the current file access.
Screen fields
Screen field |
Description |
Starting values case |
Whether PEEK should translate starting values for alphanumeric fields to
uppercase or not. |
Null starting value |
When building a starting value for a key (or component) that has not been
entered by the user, PEEK will use the default format for the key type. However,
if a key is defined as an alpha but is redefined within NATURAL to be of a
different format (usually as one or more packed fields), then the database
access will not begin from the desired position. To overcome this problem,
PEEK allows the user to specify hex nulls (H'00') as the filler character
instead of the default spaces (H'40'). |
Compress PE histogram |
When using a histogram on a key within a periodic group, ADABAS returns
information separately for each PE occurrence. This option allows the user
to combine all occurrence information into a single line. |
Show sub/superdescriptors |
Whether or not the sub- and superdescriptors should be shown on the browsing
screens. |
Show MU/PE fields on EL screen |
Whether or not the multiple value and periodic group fields should be displayed
on the single-record elementary browsing screen. |
Maximum WHERE rejections |
When using WHERE criteria, it is possible that large numbers of records may be
rejected before enough records are found to fill the record buffer. The value
specified here controls how many records can be rejected before PEEK will ask
the user whether they want to continue with the current access. |
Single-record fld names width |
This parameter applies only to the single-record browsing screen. It effectively
shifts the display of each field's output to the specified column. |
Multi-record min field width |
The minimum field width for fields on the multiple record screen. PEEK will
truncate the field name if it is wider than this value, so some fields may be
difficult to identify. If this field is set to '0', PEEK will always display
the full field name. |
Multi-record MU/PE lines |
Multiple value and periodic group fields show only the first occurrence by
default. You may alter the number of occurrences to three or five with this
setting. |
File user-exit |
This setting determines whether any of the field on the current file should
be modified by a user-exit. Specify here the
name of a Natural subprogram which will be called before displaying certain
field's data on the screen. |
Prefix to be suppressed |
Each field name on the file will be checked to see whether it begins with
the value specified in this field. If it does, the suffix will be suppressed.
For example, if several fields on a file begin with the text 'DATE-',
then enter that string into this field to suppress it from the display. This
will make your browsing screens less cluttered and easier to read. |
