Is it possible in SPlus to create simulated data based on a defined
covariance table?  I want to create a simulated data set for
dichotomously scored items and have the items inter-correlated.  For
example,


Item       1     2     3      4      5
1            -   .44    .37   .67   .51
2                  -     .49   .39   .62
3                         -     .74   .53
4                                 -     .47
5                                         -


The raw data I want to simulate would consist of 1s and 0s for each
item to represent correct and incorrect scores.  It would be further
helpful to be able to specfiy average score by examinee, average score
by item, and a point biserial for each item.  Anyone know if such magic

can be pulled off in SPlus?
