    Dear $all,

    this probably is a nobrainer – but my attempts to solve it with my share of brain cells yielded no favorable results:

    Instead of the 2 lines:

    Do myList.$load(RecId) ## load record with ID...
    calculate myValue as myList.myField

    to get myValue, I would like to do this in one line like this

    calculate myValue as myList.$load(RecId).myField

    I guess it has to do with () (brackets for evaluate this first, then that…)), but I’ve done every sensible permutation of bracketing – alas, to no avail 😳.

    Maybe crowd sharing brain cells will bring the answer…

    Thanx in advance!

    Hello Uwe,

    I do not think that will work and this might be for two reasons. A list can have more than one line and therefore when having a list you will always need to tell which line you want the data from. But even then I do not think this will work.

    However to achieve a one liner you could encapsulate the method inside the object:

    1. make a new method in the table class, i.e. $getName

    2. this method should receive your ID and possibly the line number (if it is not a row).

    3. This could be the code:

    Do $cinst.$load(pIdent)

    Quit method $cinst.[pLine].name

    4. Then the code to call this would be like:

    Do myList.$getName(RecID,LineNo) Returns myValue


    Calculate myValue as myList.$getName(RecID,LineNo)

    Does that help?

    Hi Andreas,

    yes, it does help – by knowing FOR SURE it doesn’t work – so I need not over strain my one brain cell ( I only have that one!), and by pointing me in the right direction. I will do a


    so I’m not limited to a predetermined field.

    Thanx a lot!

      Hi Uwe,

      great! Good idea to put it into the super class.

      Do not forget to consider the line number. If no current line is set it will be null otherwise.
