[LON-CAPA-users] carrying parameters between problems...?

  Yes.... I have tried this, but in CSTR there seemed to be difficulties 
with the imported script library.

Two questions:

1) I take it that the script snippet you showed (below) is meant to be at 
the front of the script library file that I import?

2) Since there seems to be some dubious messing around associated with 
trying this, I think I will probably opt for having a really long multipart 
question instead.
Do you foresee any difficulties with using an 18-part problem? (other than 
the great annoyance of possibly having to set parameters for all of those 
parts... ).  I have already created such a problem and it seems to work, 
for me,  but I wonder about its general usability.  Possibly might cause a 
log jam?

Thanks,
Ray
