Richard & Raynald:

Thanks much for your advice. After some experimentation, I ended up running
the appended syntax (adapted from Raynald's DO REPEAT code) on my laptop.
Based on the times between successive SHOW commands it took about 5 minutes
30 seconds to run for all 4788 vars and 40 cases (consistent with Raynald's
observations). Thanks too for your advice re: cache and workspace -- VERY
helpful.

Also, for others who like me know little programming and are reading this
post, I found it helpful to look over the descriptions of macros in
Raynald's book and Sarah Boslaugh's book (sage publications) to really
understand Raynald and Richard's code.

Thanks!
