Explain about sub
files in AS/400.
If we want to access multiple
records, then we have to go sub-files. There are three types of sub-files.
i.
Load all by this method we have to load only 9999
records. Here the page up and
page
down has been control by system. In this method sub-file size is greater than
sub-file page.
ii.
Load on demand
[SIZ>PAG] by this method we can load only 9999 records. Here
the page up
control can be controlled by system and user controls the page down. In
this
method sub-file size is greater than sub-file page.
iii. Load on demand [SIZ=PAG] by the method we can load unlimited records.Here user
controls both of the Page-up and Page-down. In this method sub-file size is equal to sub-
file page. This type is more advantage
