Deleting entire file

Deleting entire file

Deleting entire file

Not good at this, as you can see, I want to read every record in FileA, Chain to FileB and if not found in FileB, delete the record from FileA. but I am deleting the entire file. sounds simple but I cant see my mistake. Please advise.



Read FileA;
Dow not %Eof(FileA);

Chain (Inv#) FileB; //field from fileA
If not %Found(FileB);
Delete FileARecFmt;
Read FileA;

*INLR = *On;


RE: Deleting entire file

I'll ask the obvious. You are sure that some file a records are in file b?

RE: Deleting entire file

Thanks for responding....It is possible filea records are not in fileb.
If filea records are not in fileb, i want to delete them from filea.

RE: Deleting entire file

Delete by key:

Delete FileARecFmt(Inv#);

I keep trying to do something about my procrastination but I keep putting it off until tomorrow.

RE: Deleting entire file

Thanks, that gets me stuck in a loop. Should I setll on fileb instead of chaining?

RE: Deleting entire file

you might try a set lower limts, but I would do a read equal. My initial question was you are sure that filea, does contain some records that need to be deleted.. so you do have some where the chain "hits"..

RE: Deleting entire file

Thank You for your help! I want to read each record in FileA, chain each record to FileB and if that filea record is not found in FileB, delete the record from FileA.
Filea should always contain records that need to be deleted, but i guess there is the possibility there wouldn't be. Tf the chain doesn't 'hit', should I do a setll on fileb instead of a chain to look for a matching record?

RE: Deleting entire file

do you know how to do a wrkqry, an IBM utility? If so,, go thru that, and pick upi records where the "key" matches,, that way you can be assured that the data is valid.Then you could try a setll and do a reade, and see what happens..
