<h1 class="topictitle1">Determine when a source statement was changed</h1>
|
|
<div><p>Each source record contains a date field which is automatically
|
|
updated by the source entry utility (SEU) if a change occurs to the statement.
|
|
This can be used to determine when a statement was last changed.</p>
|
|
<p>Most high-level language compilers print these dates on the compiler lists.
|
|
The Copy File (CPYF) and Copy Source File (CPYSRCF) commands also print these
|
|
dates.</p>
|
|
<p>Each source member description contains two date and time fields. The first
|
|
date/time field reflects changes to the member any time it is closed after
|
|
being updated.</p>
|
|
<div class="p">The second date/time field reflects any changes to the member. This
|
|
includes all changes caused by SEU, commands (such as CRYF and CPYSRCF), authorization
|
|
changes, and changes to the file status. For example, the FRCRATIO parameter
|
|
on the Change Physical File (CHGPF) command changes the member status. This
|
|
date/time field is used by the Save Changed Objects (SAVCHGOBJ) command to
|
|
determine if the member should be saved. Both date/time fields can be displayed
|
|
with the Display File Description (DSPFD) command specifying TYPE(*MBR). There
|
|
are two changed date/times shown with source members: <ul><li><samp class="codeph">Last source update date/time</samp>. This value reflects any
|
|
change to the source data records in the member. When a source update occurs,
|
|
the <samp class="codeph">Last change date/time</samp> value is also updated, although
|
|
there might be a 1- or 2-second difference in that date/time value.</li>
|
|
<li><samp class="codeph">Last change date/time</samp>. This value reflects any changes
|
|
to the member. This includes all changes caused by SEU, commands (such as
|
|
CPYF and CPYSRCF), authorization changes, or changes to file status. For example,
|
|
the FRCRATIO parameter on the CHGPF command changes the member status, and
|
|
therefore, is reflected in the <samp class="codeph">Last change date/time</samp> value.</li>
