RE: RLU - Dynamic generation of report layout

["Fisher, Don" <Dfisher@xxxxxxxxxxxxxxxxx>]

Okay, so you're looking for a way to make a report recognize fields added to
a physical file and include them using an externally described printer file?
I don't have an answer to the externally described printer file issue,
unless you want to get into programatically modifying DDS source.

The easiest way to accomplish dynamically building the report might be to
use DSPFFD <filename> *OUTFILE and then have the RPG program build an array
or multi-occurrence data structure of the fields, column headings, lengths,
and attributes.  The program can then populate a unformatted field of 198
characters with the column headings, ensuring the width of the column
heading matches the total width of the field.  From there, the same field
can be used in conjunction with EVAL and %EDITC to build a formatted report
line by using the attributes of the field (character, packed, signed, zoned)
to determine whether the field should be edited.

For this to work, of course, you either have to have the file to which
fields are being added compiled with LVLCHK(*NO) or ensure the program is
recompiled each time fields are added.

Hope that helps.

Now there are reports based on this file which will use some fixed fields
and some added fields. We are using RLU for designing reports.

In PF we can add more fields but in RLU since you design the layout then at
the runtime how can we amend the RLU design.
