Does anyone know of the limitations of recursive procedure calls in 4D? is 
there any? I am programming a MLM, where a distributor sponsurs another 
distributor and so on and so on... When it comes to doing the calculations
and/or printing of reports it would be nice to write a resursive procedure
that steps down the tree and either calculates totals or prints the records.
At most I will have to go six levels deep. Has anyone done this in 4D?

On a similar note, when doing the report for the above, I would like to 
combine different layouts on the same report which should be pretty
easy to do with PRINT LAYOUT. I am unsure as to how to trap for the header 
and footer though. When do the in Header and in Footer flags get set. I imagin
I would start with somthing like this:

print layout ([anyfile];"Header")
..
`for each record
print layout ([anyfile];"body") 
..
print layout ([anyfile];"footer")
form feed


This above procedure will print a header on the first page and a footer on 
the last page but nothing other than data lines on the rest of the pages. 
How can I trap for headers and footers on the other pages?

Thanks for any info you can provide.
