simplifying code…
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.myFieldto 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
or
Calculate myValue as myList.$getName(RecID,LineNo)
Does that help?
Best,
Andreas

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
taSuper.$getValue(pSchema,pID,pFieldName)
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.
Best,
Andreas
