Josh,
the two functions are just a tiny example of what I want to do which is:
call a function with 2 or more arguments (v_val1 and v_val2).
The called function (test2() in the example) will MODIFY the two arguments
and then return a true value. After test2() has run, the value of the two
arguments 'has changed' to what test2() has assigned to them.
I know that this might not be good programming practice since many
applications rely on functions NOT changing the variables which get passed
to them as arguments. maybe if we could specially declare them as
'changeable' parameters ...
The functionality of 'returns record' is nice to have but it would not help
me in this case. I would have to create a record each time I want to pass
more than one value back to the calling procedure. This means 'disk access'
which is another word for 'this is going to slow down my program'. But this
reminds me: where are temp tables kept? On disk or in memory? - that might
be a way out of the dilemma.
Best regards,
Chris
