"Left" data values that don't come from the + active file naturally stay the same from case to case, because the + procedure code keeps using that same case. + + One of the compromises that comes with the new procedure code is + that the active file allocates and provides its own case, which + the procedure code then has to resize to provide room for any + other variables that should go in the case and then fill in the + values of "left" variables. Then, when we're done with that case, + we have to save the values of "left" variables to copy into the + next case read from the active file. + + The caseinit code helps with this. + + * automake.mk: Add new files. + + * caseinit.c: New file. + + * caseinit.h: New file. + +2007-06-06 Ben Pfaff + + * value.h (value_cnt_from_width): New function. + + * variable.c (var_get_value_cnt): Use new function. + +2007-06-06 Ben Pfaff + + Add casegrouper, to allow cases read from a given casereader to be + broken into groups, each of which has its own casereader. + Generally cases are grouped based on having equal values for some + set of variables. + + * automake.mk: Add new files. + + * casegrouper.c: New file. + + * casegrouper.h: New file. + +2007-06-06 Ben Pfaff + + Add interface to lexicographical ordering of cases. + + * automake.mk: Add new files. + + * case-ordering.c: New file. + + * case-ordering.h: New file. + +2007-06-06 Ben Pfaff + + Add casereaders and casewriters, the basis of the new data processing + implementation.
