Data Loader: Decimated 3D surveys with variable line lengths may load incorrectly

Description:
SYMPTOM:    Data Loader: Under certain loading definitions, a decimated 3D survey 
with variable line length is not loaded correctly.  The problem is encountered when the
inline numbers are 1,2,3,4,5,..., the CDP numbers are 1,2,3,4,5,..., and the user wants to
load inline 1,3,5,7,.., and CDP 2,4,6,8,..  If the integrity check is used, only the first Inline 
is loaded.  All subsequent lines load with blank traces and the first line will have 
incorrect CDP numbers. If the integrity check is turned off, the lines will load properly,
but will have incorrect CDP numbers.  
  

Solution:
WORKAROUND: If possible, load un-decimated data.
          
RESOLUTION: Corrected in IESX 10.1, released in December, 1996.
