Creating a new descriptor
Looking again at the Descriptor listbox in Description
tab , you should notice that only the first
entry is an actual descriptor. The remaining selections, which are
all enclosed in angle brackets and all begin with the word
new
,
are for creating new descriptors. Here is the list from Description
tab:
For example, if you clicked <new string descriptor>, the Macro
object would create a new String descriptor and place it at the start
of the list. The lower area of the Description tab would allow you
to fill out the various fields that belong to a String descriptor
(such as a row and column location and a character string). The Descriptor
listbox would then look like this:
In the figure above, the currently selected descriptor is now
the
String descriptor
at the top of the list (the 3,29
stands
for row 3, column 29). The Field Counts and OIA
descriptor
is now second on the list.For information on how the macro runtime handles multiple descriptors, as in the figure above, see Evaluation of descriptors.
