Re: Going slowly insane, or keyed file continued

Amy, asuming your file looks more or less like the following:

File: AmyFile

    R RECORD
        FLD1         1A
        FLD2       10A
        FLD3     117A
    K FLD2

Could you define a logical over it as follows: ?

File AmiLog
                                         UNIQUE
    R RECL                        PFILE(AmyLib/AmyFile)
        FLD1           1A
        FLD2A8       8A   I    SST(FLD2 1 8)
        FLD2A2       2A   I    SST(FLD2 9 2)
        FLD3        117
    K FLD2A8

The "I" in FLD2A8 and FLD2A2 stands for "Input only" as being a substring of a 
real field
cannot be defined as updat_capable... I don't remember its exact position, but 
should be
more or less where I've put it...

In this way, you can go on working with your normal "Amyfile", but the system 
will check
there are no duplicate values in the first 8 chars of FLD2 since AmiLog is 
defined as
UNIQUE ...

Hope this helps, Antonio
