>Where does "spanned" come into play? Why does that make the difference?
An acronym conflict! I hate IBM's tendency to use the same letters (in the same position) to mean different things! vbS -- Variable Blocked Spanned fbS -- Fixed Blocked Standard (BTW: why "Standard"? What the H-E-Double-Toothpicks does that mean?) They did a similar thing with: PCB -- before I ever even became aware of IMS it meant (to me) Printed Circuit Board. ATM -- I thought it meant Automated Teller Machine. - Ted MacNEIL eamacn...@yahoo.ca Twitter: @TedMacNEIL ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
