However, it does not explicitly say whether the RDW or SDW limit applies when the segment control field is 00." and that nobody answered the question. Have you verified that for VBS an SDW with a zero segment control field is treated as an RDW, and thus allowed to specify a zero length?
I just ran a series of tests, writing a VB data set, then a VBS data set, with various data lengths from 0 to 20, once with move mode and once with locate. All ran fine. Then I ran analogous tests reading the data sets, and dumping the input; an additional read with BFTEK=A also worked correctly.
So the description doesn't match QSAM behavior; is it possible the author was thinking of compiler library code?
