SYMPTOMS

Specifying a scope for a report to print does not print the correct records from the table.

CAUSE

The problem is that the DataEnvironment object created when the report was created performs an implicit GO TOP command as it initializes, even if the table is already open. This is necessary so that programmatic changes to Cursor object properties, such as Filter, take effect. A unexpected side- effect of this recent change is that the Scope clauses (ALL, NEXT, RECORD, and REST) on the REPORT FORM command do not affect which the records are printed.

For example, if you have a table open and the record pointer is sitting at record 5, a REPORT FORM <x> NEXT 1 should print record number 5 only. However, because the DataEnvironment object performs a GO TOP command, the record pointer is re-positioned as the DataEnvironment object is initiated, so record number 1 prints - not 5.

WORKAROUND

To use the REST, RECORD, and NEXT Scope clauses on the REPORT FORM command, you must prevent the implicit GO TOP command performed by the DataEnvironment object, which can be done in any one of these ways:

Remove the table from the DataEnvironment object, and open it before running the report. -or-
Keep the table in the DataEnvironment object, but set the AutoOpenTables property to false, and open the table manually before running the report. -or-
Keep the table in the DataEnvironment object, and save and restore the record pointer before the report actually prints. To do this:
1. Set AutoOpenTables to false for the DataEnvironment object.
2. In the Init event, do the following:
```
      x=0               && Create a scoped variable
      this.opentables   && Call the OpenTables method
      go (x)            && Restore the Record pointer
								
```
3. In the OpenTables method, save the record pointer:
```
      x=RECNO()
```

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

Code to Reproduce Problem

create table repotest (mychar c(1))
insert into repotest values ('1')
insert into repotest values ('2')
insert into repotest values ('3')
insert into repotest values ('4')
insert into repotest values ('5')
create report repotest from repotest
 
goto 2
REPORT FORM repotest next 1  &&Record 2 should print but record 1 prints
