|

|
|
<div><p>Use this field-level keyword in the subfile control record format
|
||
|
|
to return the relative record number of the subfile record that is at the
|
||
|
|
top of the subfile when control is given back to your program.</p>
|
||
|
|
<div class="section"><p>This keyword has no parameters.</p>
|
||
|
|
<p>This field must have the
|
||
|
|
keyboard shift attribute of signed numeric with zero decimal positions. It
|
||
|
|
has to be 5 digits in length, and it must be defined as a hidden field. The
|
||
|
|
hidden field will not display an input field on the screen.</p>
|
||
|
|
<p>This field
|
||
|
|
is returned to your program as part of the input for this subfile control
|
||
|
|
record. If control is returned to your program by pressing the enter key,
|
||
|
|
then the value returned will be the relative record number of the top subfile
|
||
|
|
record currently displayed.</p>
|
||
|
|
<p>With the ROLLUP or ROLLDOWN keywords, control
|
||
|
|
is returned to the program when pressing a Page Up or a Page Down key will
|
||
|
|
page beyond the end of the subfile. Without ROLLUP or ROLLDOWN, a message
|
||
|
|
is displayed. If control is returned to your program because of the ROLLUP
|
||
|
|
keyword, then the value returned will be the relative record number of the
|
||
|
|
top subfile record on the next page. If control is returned to your program
|
||
|
|
because of the ROLLDOWN keyword then a 1 will be returned in the relative
|
||
|
|
record number field.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> The ROLLUP keyword is the same as the PAGEDOWN
|
||
|
|
keyword and the ROLLDOWN keyword is the same as the PAGEUP keyword.</div>
|
||
|
|
<p>SFLSCROLL
|
||
|
|
is not allowed when SFLSIZ equals SFLPAG.</p>
|
||
|
|
<p>This keyword is valid only
|
||
|
|
for the subfile control record format.</p>
|
||
|
|
<p>This keyword is helpful when
|
||
|
|
scroll bars are used. (When SFLEND(*SCRBAR) is specified.) When the user interacts
|
||
|
|
with the scroll bar, the hidden field that contains SFLSCROLL contains the
|
||
|
|
relative record number of the record the user wants displayed. Control will
|
||
|
|
only be returned to your program when the user attempts to scroll into parts
|
||
|
|
of the subfile that are not written to or if the enter key is pressed. Another
|
||
|
|
keyword that might be useful is SFLRCDNBR will *TOP as a parameter. After
|
||
|
|
you have added records to the subfile, redisplay the subfile with the SFLRCDNBR
|
||
|
|
in effect. Use the same number for this keyword that was returned to the SFLSCROLL
|
||
|
|
keyword.</p>
|
||
|
|
<p>You cannot specify the SFLROLVAL, the SFLSCROLL and the SFLRCDNBR
|
||
|
|
keywords for the same field.</p>
|
||
|
|
<p>Only one SFLSCROLL keyword is allowed in
|
||
|
|
the subfile control record.</p>
|
||
|
|
<p>Option indicators are not valid for this
|
||
|
|
keyword.</p>
