<p>The Move the Resume Cursor to a Return Point (CEEMRCR) API moves the resume
|
||
|
|
cursor to a return point relative to the current handle cursor.</p>

|
|
|
||
|
|
<p>Initially, the resume cursor is positioned after the machine instruction
|
||
|
|
that caused the condition to be raised. The direction of movement is always
|
||
|
|
toward older call stack entries.</p>

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>If you attempt to move the resume cursor with a type_of_move of 0 and the
|
||
|
|
resume cursor and the handle cursor are at the same call stack entry, the move
|
||
|
|
is not valid.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>The actual movement of the resume cursor occurs only after the condition
|
||
|
|
handler returns to the condition manager. If two or more calls from a given
|
||
|
|
user-written condition handler set the resume cursor to different places, the
|
||
|
|
most recent call will be used.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>When a return operation is made to the condition manager after the resume
|
||
|
|
cursor is moved, any associated exit procedures are called for each call stack
|
||
|
|
entry that is passed. Moving a resume cursor past a call stack entry also
|
||
|
|
cancels any associated user-written condition handlers.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>Ensure that the CEEMRCR API is called before handling the condition. A call
|
||
|
|
to the CEEMRCR API is not valid if there is no active condition. For example,
|
||
|
|
the condition may not be active if the condition handler uses the message
|
||
|
|
handler API, Change Exception Message (QMHCHGEM), to handle the condition.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>When doing a type 1 move, the exception message is immediately moved to the
|
||
|
|
call message queue of the call stack entry one older than that indicated by the
|
||
|
|
handle cursor. Therefore, when using APIs to perform some action on the
|
||
|
|
exception (for example, QMHCHGEM), you must indicate a target invocation of one
|
||
|
|
older than the original handle cursor.</p>

||
|

||
