Students store data relative to the scripts.
E.g.,
coursefolder
scripts
data
temp
Now gretl will search for data relative to the
script directory, so on Windows they can use
open ..\data\mydata.gdt
But now suppose they try the obvious:
store ..\temp\tempdata.gdt
This does not work, because store presumes
this is all relative to the working directory.
Students are often using lab computers with
network drives or flash drives, so it works
best if everything is relative to their
scripts directory.
Things are actually worse than this. Suppose
they try
store tempdata.gdt
open tempdata.gdt
Now `store` will store this in the working directory,
but `open` will first look relative to the script,
so if there is also a `tempdata.gdt` in `classfolder`scripts`
they will open that by mistake!
Hope that's illustrative,
Alan
