Betr.: 20 variable limit in $INPUT
Dear Andreas,
Isn't the limit you're referring to the maximum amount of etas/thetas, these
can be adjusted (see: http://www.icondevsolutions.com/nonmem_tip20.htm )
As far as I known the amount of data items can not be adjusted. If some of them
are not in use, you can use the DROP data item. The complete column will be
removed in the analysis.
" If DROP (or SKIP) is used as a data item label or synonym, the data
item type will not appear in the NONMEM data set. DROP (or SKIP) may
be used with more than one item."
Cheers,
Rob

I am looking for a solution to get around the limit of 20 input variables
in nonmem.
The message you get with more than 20 variables in $INPUT is this:
16 $INPUT: NO. OF DATA ITEMS EXCEEDS 20.
STOP 4 statement executed
I did not find anything in the archives or on the Web. I recall having
successfully done that in nonmem V, and I think it was about changing the
value of 20 to another value in a few files.
My original naive idea was that this was just a single change to the SIZES
file in nm VI but that seems to not be the case.
To keep the discussion focused, I am not looking for workarounds like
solutions with concatenated values and an indicator variable.
For a change I am trying to get the software to adapt to the user's needs
instead of the usual opposite situation.
Thanks for any pointers.
Andreas
