CA Verify for VTAM starts a new row on your display for every 3270 order in the screen. If there are no orders, only one row is displayed. Data that follows the order appears under the ruler. Non-3270 data streams are displayed in 40-byte rows.
A common sequence of orders is set buffer address (SBA) followed by start field (SF). To condense the display, CA Verify for VTAM merges these orders into an FLD order type.
Each row in the display consists of:
The 3270 order. This will be blank for the first field if the screen does not begin with an order. The most common orders are summarized next. See the 3270 Component Description or Programmer's Guide for a complete description of valid orders.
Set buffer address specifies the row and column for the data which follows.
Start field specifies the beginning of a field and its attributes.
Insert cursor specifies cursor positioning in the current row and column.
Repeat to address repeats the first character that follows up to the specified row and column.
Program tab specifies the next unprotected field as the location for the data that follows. If there is any data between the program tab order and the previous order, all fields between the current display position and the destination field are set to nulls.
Erase unprotected to address sets all unprotected fields from the current display position up to the specified row and column to nulls.
The row specified by the order.
The column specified by the order.
The field attributes specified by a start field order:
Unprotected field — can be modified
Protected field — cannot be modified
Numeric field — only numeric data can be typed
Cursor will auto-skip over the field
High-intensity field
Field can be selected with a selector pen
Low-intensity (non-display) field
Field with modified data tag which will be transmitted from the terminal even if the operator makes no entry
The length of the data following the order.
The actual data appears next beneath the ruler.
