index object idxinfo.pvc

[Peter.Higgins]

Can anyone tell me if the null suppression on the last segment for a Primary internal key is in anyway related to the K: or N: attributes in the index object? 

! IF POS("N"=COLUMNATTR$) THEN IDXINFO'COLUMNATTR$="N",IDXINFO'COLUMNNULLCHARACTER$=MID(COLUMNATTR$,POS("N;"=COLUMNATTR$)+2,2),BuildColumnAttr$+="N"
! IF POS("K"=COLUMNATTR$) THEN IDXINFO'NULLSUPPRESS=1,IDXINFO'NULLCHARACTER$=MID(COLUMNATTR$,POS("K;"=COLUMNATTR$)+2,2),BuildAttr$+="K"
