LOOPING THROUGH THE BLOCK

Question

Can anybody help me with an example or materail which explains how can we loop through a block in Forms 6i?
Also how we can loop through the details block pertaining to the master block and process those records also?
Thanks

The quickest way to do something is not to do it at all, and this looks like a good example of where you don't need to do anything - what I suspect you really need is a better design for your schema. What are you updating that requires an update on all child records and cannot simply be referenced when you query a child record?
If you can't change the schema and you have millions of records to update then your best bet is to use sql, then try pl/sql if sql can't do the job. Only try forms if you absolutely have to, and expect it to run like a brick.
In forms (assuming you're using relationships):
go to each block, do first_record and process each record.
go to the lowest child block and loop through the records using next_record until "system.last_record = 'TRUE'", processing each record as you go.
go to the next block up, do next_record and process that record.
go back to the lowest child block and loop though it, processing each record.
when you have reached the last record in the penultimate child block then go to its immediate parent block, do next_record and process that record.
go to the lowest child block etc etc etc
There are a lot of things which you can do in forms but which belong on the database!
