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:
m )

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."

I am looking for a solution to get around the limit of 20 input =
in nonmem.
The message you get with more than 20 variables in $INPUT is this:

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 =
value of 20 to another value in a few files.
My original naive idea was that this was just a single change to the =
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 =
instead of the usual opposite situation.

Thanks for any pointers.
