Re: F Specs on an OVRDBF

Create a logical keyed by vendor and read equal(READE) on the vendor you
want in your maintenance program and only present those records.

No OVRDBF needed.      DON'T use a Select/Omit logical.

John Carr




I have a product master file (P701).  I had to write the online maintenance
in such a way that when the DP clerk selects product maintenance they are
prompted as to which vendor they wish to do maintenance on.  So only those
products with that particular vendor code are accessible through
maintenance.  I created two logicals utilizing the select.  One for each
vendor.
I know I can do it with BLDQRYSLT, but I prefer to try to utilize OVRDBF in
my CLP.  I have only been programming for a year.  I am self taught and I
want to get a better grasp on this OVRDBF.  My boss allows me to learn
everything I can, to try new approaches whenever possible, and get exposure
on all that RPG, CL, and SQL has to offer. (RPGIV is coming soon). That is
why I am choosing OVRDBF (if it is possible).
My question is (because my boss is on vacation) what do my Fspecs need to
look like?  I have looked in all the manuals and infoseeker but I can't
find
this info.
I am thinking my CL should be:
OVRDBF (PFILE) TO (VENDOR CODE SPECIFIC LFILE)

Should my Fspecs contain only the PFILE (update) or do I need the
LFILE's(input) in there also?

Am I even close with this?  Am I wrong in thinking that it can be done this
way?

Thank you in advance for any info or insight you can shed on this matter.
