<p>The Set Cursor Address (QsnSetCsrAdr) API sets the position of the cursor on
|
||
|
|
the screen. The display address is not affected by this command if this is an
|
||
|
|
indirect operation and the target command buffer contains an active Write to
|
||
|
|
Display (WTD) command. Otherwise, a WTD command will be inserted that resets
|
||
|
|
the display address to row 1 column 1.</p>
|
||
|
|
|
||
|
|
<p>This command corresponds indirectly to the 5250 Write to Display command
|
||
|
|
(WTD) with an Insert Cursor or Move Cursor order. (For an indirect operation, a
|
||
|
|
WTD is placed in the command buffer only if one does not already exist in that
|
||
|
|
buffer.) The Move Cursor order is used if the control unit supports it (based
|
||
|
|
on the 5250 Query command). Otherwise, the Insert Cursor order is used.</p>
|
||
|
|
|
||
|
|
<p>If the Move Cursor order is supported, this API sets the cursor without
|
||
|
|
modifying the home address and without regard to the state of the keyboard.
|
||
|
|
Otherwise, the behavior is the same as that of the Insert Cursor (QsnInsCsr)
|
||
|
|
API.</p>
|
||
|
|
|
||
|
|
<p>If multiple QsnSetCsrAdr operations are applied to the same command buffer,
|
||
|
|
only the last QsnSetCsrAdr operation is in effect. The last QsnSetCsrAdr or
|
||
|
|
QsnInsCsr operation determines the cursor position. If the Move Cursor order is
|
||
|
|
used, the QsnSetCsrAdr negates any previous QsnInsCsr commands in the command
|
||
|
|
buffer, except for the last QsnInsCsr, which sets the home position. If the
|
||
|
|
Insert Cursor order is used, it negates any previous QsnInsCsr operations. If
|
||
|
|
the Move Cursor order is supported, you can set the home position and then move
|
||
|
|
the cursor by issuing a QsnInsCsr first, followed by a QsnSetCsrAdr
|
||
|
|
operation.</p>

|

|
<p>The field ID indicating the field at which to set the display address. If
|
||
|
|
this parameter is specified with a nonzero value, the row and column parameters
|
||
|
|
are ignored and the row and column values corresponding to the field ID are
|
||
|
|
used to set the display address. Either the field ID or the row and column
|
||
|
|
parameters must be specified.</p>
|

<dd>INPUT; BINARY(4)
|

|
|
|

|
|
<p>The row at which to position the cursor. The row parameter must refer to a
|
||
|
|
row no greater than the current screen or window mode height (if window mode is
|
||
|
|
enabled). The actual screen row used for a screen I/O operation is calculated
|
||
|
|
using the formula base+offset=actual. The base is the row location of the top
|
||
|
|
window border (0 for full screen) if offset is positive, or the row location of
|
||
|
|
the bottom window border (screen height plus 1 for full screen) if offset is
|
||
|
|
negative. The offset is the row parameter value specified, and actual is the
|
||
|
|
actual screen row to be used. A CPFA307 error occurs if an incorrect row value
|
||
|
|
is specified.</p>

<p>The column at which to position the cursor. The column parameter must refer
|
||
|
|
to a column no greater than the current screen or window mode width (if window
|
||
|
|
mode is on). The actual screen column used for a screen I/O operation is
|
||
|
|
calculated using the formula base+offset=actual. The base is the column
|
||
|
|
location of the left window border (0 for full screen) if offset is positive,
|
||
|
|
or the column location of the center window border (screen width plus 1 for
|
||
|
|
full screen) if offset is negative. The offset is the column parameter value
|
||
|
|
specified, and actual is the actual screen column to be used. A CPFA307 error
|
||
|
|
occurs if an incorrect column value is specified.</p>

parameter is omitted or specified as 0, this is a direct operation and the

cursor is positioned at the specified location immediately. Otherwise, this is

an I/O operation taking place.</p>
