Iris,

SWMM44h (may, 2002 version), SWMM44g and SWMM44gu all read and print the
detailed printout the same in sample test data sets. It may be that
some other B line in Extran is affecting the printout in your data file
using SWMM44h. It would help if you could send the snippet of your
input file going from the SW lines to the first C1 line.
