Re: Re: Pdesk Manual Question 3

Each app keeps its own set of category names. Each app also keeps a 4 bit
wide set of integers which are used in records to represent which of the 16
category names stored by the app apply to this record.

The numbers are assigned in no particular order. So, If another app wants to
create a record in the ToDo pdb with a category which matches one of its
own, it has to go digging about inside the ToDo db to figure out if 1) any
of the ToDo Categories match the string it has, and 2) which integer is used
to represent that ToDo category.

I am not sure if the API makes this search hard or does not even provide the
function. For whatever reason, almost no-one tries to keep the categories
consistent across apps.

Hope that helps. :-)
