Access arrays by using the internal Element(arrayname, dim1, dim2, dim3, dim4)
function. The Element function's usage is the only aspect of QView's user interface
that varies between some versions of Clarion. In C5 and C55 (despite the
documentation) parameters after the first could be omitted in bound functions. In C6
and early versions of C7 that was not the case. The behaviour was restored in a late
build of C7.2. So, for c5, c55, late 7.2 and 7.3 onwards it's not necessary to include any
"trailing and ignored" dimensions in your filter.
The Element function will fail (and cause an evaluation error) if passed a label that has
no dimensions or the dimensions are out of bounds.
Another internal function records() is available but not offered in the toolbox. It
enables you to filter based on the number of records in a referenced queue (null
references are treated as empty queues). If your queue reference had label
MyQueueRef, an example is:
Records('MYQUEUEREF') > 123
Note (like the Element function) the label must be quoted.
Load
Makes a call to QVRestore, any suitable captured or archived queues can be selected
and appended to the current queue:
See the Edit menu topic for a slightly more long-winded explanation of why it is safe
to play with this feature - you are working with a copy of your program's queue.
Capture
Adds the current queue to the capture list. Captured queues are available for the
duration of a debugging session.
Archive
Archives the current queue to disk. Archived queues are available in the current and
subsequent debugging sessions. They can be removed from the Queue Restore
window (above).
Show All
Start the "show me all captures and archives" window. From there you can view other
queues or remove captures and archives:
Basic Table
Writes a delimited file using current filter, pictures and array settings. Options to
change delimiter, exclude column names etc:
Clipboard
Writes tab-delimited output to the clipboard using current filter, pictures and array
settings. Suitable for pasting into Excel.
Source
Displays the queue's structure:
XML
Crude 'export Queue to XML' feature.
Disable QView
It is easy to get yourself into a tight loop making repeated calls to (say) QVEdit. Use
this option to disable QView for the rest of the session (confirmation required).
