<p>The Pad for N Positions (QsnWrtPad) API pads the display with the given pad
|
||
|
|
character for the specified number of bytes. Padding starts at the row and
|
||
|
|
column specified, or at the current display address if these parameters are
|
||
|
|
omitted. To allow the QsnWrtPad operation to insert a group of characters
|
||
|
|
without overwriting the ending screen attribute, the following conditions must
|
||
|
|
be satisfied:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The operation is an indirect operation.</li>
|
||
|
|
|
||
|
|
<li>The row and column parameters are omitted.</li>
|
||
|
|
|
||
|
|
<li>The low-level environment description does not indicate that DBCS data is
|
||
|
|
being used.</li>
|
||
|
|
|
||
|
|
<li>The previous command saved in the command buffer was a Write Data
|
||
|
|
(QsnWrtDta) operation.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>If the row and column parameters are omitted and the command is either a
|
||
|
|
direct operation or the buffer specified does not contain a preceding output
|
||
|
|
operation that sets the display address, then the current display address is
|
||
|
|
set to row 1, column 1, prior to writing the pad characters.</p>
|
||
|
|
|
||
|
|
<p>If the from-row and from-column parameters are specified, this command
|
||
|
|
corresponds indirectly to the 5250 Write to Display (WTD) command with a Set
|
||
|
|
Buffer Address order. (For an indirect operation, a WTD is placed in the
|
||
|
|
command buffer only if one does not already exist in the buffer.)</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. If neither the field ID or row and column

<p>The row at which to write the first pad character. 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>If both the from-row and from-column parameters are omitted, the pad
|
||
|
|
characters are written starting at the current display address. If this is the
|
||
|
|
case and the command is a direct operation, or the buffer specified does not
|
||
|
|
contain a preceding output operation that sets the display address, the current
|
||
|
|
display address is set to row 1, column 1, prior to writing the pad characters.
|
||
|
|
Both the from-row and from-column parameters must be specified, or both
|
||
|
|
parameters must be omitted.</p>

<p>The column at which to write the first pad character. 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 pad

characters are written to the screen at the current display address. Otherwise,
