[Limdep Nlogit List] import text files

[Tomas Nilsson]

Hi NLOGIT users,
I've a dataset with ~70,000 observations and ~50 variables. The
dataset is created in MS Access. I've exported the table as a text
file (tried all possible file formats; even through SAS: first import
then export as text file). I've been trying to import the dataset into
Nlogit 4.0.1. The problem is that only ~20 variables are imported.
I've adjusted the memory via Tools -> options and Project -> settings,
but still not successful. Any advice?

Thanks,

Tomas
