FIND function

martinher562

I am still confused as to what the find function does.

There is a report that has an integer table and the variable of WhseEntry as a record using subtype Warehouse Entry.

In the interger table; in the PreDataItem() trigger, it says the following:

Integer - OnPreDataItem()
CLEAR(Location);
WhseEntry.RESET;


IF NOT WhseEntry.FIND('-') THEN
CurrReport.BREAK;


What does this mean ??????? !!!!!!
Does it just say, if you cannot find first record (at least one record) then break the report ?
I read this, but is not very helpful.

FIND Function is used to retrieve records from table. You can filter the records you want to retrieve from the table using SETRANGE/SETFILTER.

FINDFIRST - Retreives First record in the table
FINDLAST - Retreives Last record in the table
FIND('-') - Retrieves all the records in the table and cursor is in first record
FIND('+') - Retrieves all the records in the table and cursor is in lastrecord

The code IF NOT WhseEntry.FIND('-') THEN
CurrReport.BREAK; means that the report processing is stopped when there is no record in WhseEntry entry table

If in WhseEntry entry table no record is found then the loop breaks for that particular record and no execution happens.
