    Hi,

    Does anyone know how to check, using SKILL, if a layer purpose pair is in
    use. ie. whether it contains any database objects or not?

    Thanks!

    I wrote a SKILL procedure that works on some examples that I tried it on. I
    think that if a LPP is in use in a database object then it should be in the
    cellview's lpps list, and if unused it should not appear there. Here it is:

    procedure(FGIsLPPUsed(lpp)
    prog(list(cv)

    cv=geGetWindowCellView()

    foreach(cvlpp cv~>lpps
    if((cvlpp~>layerName == car(lpp) && cvlpp~>purpose == cadr(lpp)) then
    return(t))
    )
    return(nil)
    )
    )

    I hope this works for you.
