Field Video Properties

Video properties control a number of terminal-dependent aspects of field display.

Video properties should be standardized across the system. However, in certain cases, you may need to deviate from the standard by specifying local video properties.

You should avoid using local video properties to specify intensity, color or highlighting unless absolutely necessary, since it represents a deviation from the system standard.

The following lists details the video properties, either standard or local, that can be defined for a field.

• Cursor Position—Indicates whether the cursor is to be placed in the field when the screen is displayed.

  The cursor identifies where the next character entered will appear on the screen.

  The possible values of this property are yes and no.

  If no fields on a particular screen have a value of yes specified for this property, the cursor will appear in the first field on the screen.

  If multiple fields have a value of yes specified, the cursor will appear in the first one on the screen (beginning in the upper left corner and working left-to-right through each row on the screen).

• Protection—Indicates whether data can be entered into a field.
• Intensity—On a terminal that supports different intensities, lets fields appear at different levels of brightness (high intensity, normal intensity, or dark, which does not appear at all).
• Color—Fields appear in any of the colors supported by the terminal.
• Highlight—Fields are displayed with any highlighting characteristics supported by the terminal, such as reverse video or blink.
• Justification—Controls the alignment of data at either the right or the left of the field. Normally, text is left-justified and numbers are right-justified.
• Blank when zero—Causes a numeric field to be displayed as blank, regardless of its edit pattern, if its value is zero.
• Fill character—Is inserted in remaining character positions after justification. For example, a value of 999 right-justified in a field five digits long with a fill character of 0 would appear as 00999.
