4     C * Version: 3.4.06 *
5     C
6     C Changelog:
7     C
8     C 3.4.05 - 3.4.06: (2005-01-12) section order wrong in CLEARSEC, fixed.
9     C
10     C 3.4.04 - 3.4.05: (2005-01-05) XE is section y odd not even, fixed.
11     C
12     C 3.4.03 - 3.4.04: (2004-12-21) bug in recognising decoding errors, fixed.
13     C
14     C 3.4.02 - 3.4.03: (2004-12-17) forget to clear esci/stwerr and vector vect
15     C plus problems with lleng (truncated vect!). Fixed the
16     C clearing, workaround for lleng (to be further investigated)
17     C
18     C 3.4.01 - 3.4.02: (2004-12-10) cleanup of the code and changed sections order.
19     C
20     C 3.4.00 - 3.4.01: (2004-11-26) CA50 comes after Strips Hit, fixed.
21     C
22     C 3.3.03 - 3.4.00: (2004-11-08) changed the DSP program hence changed calunpack
23     C to better find the calorimeter sections.
24     C
25     C 3.3.02 - 3.3.03: (2004-11-08) changes in the commons (one more common for
26     C calpulse and from calstripshit to calstriphit).
27     C
28     C 3.3.01 - 3.3.02: (2004-10-19) italian name of subroutines translated to
29     C english. Forgot to clear vector in case of CRC errors,
30     C fixed. stwerr is integer not real! fixed
31     C
32     C 3.3.00 - 3.3.01: (2004-10-18) forgot to clear stwerr if no sections are found
33     C fixed.
34     C
35     C 3.2.00 - 3.3.00: (2004-10-15) enanched search of sections in case of one or
36     C more missing sections.
37     C Switched to c function "fillin" to create calorimeter words
38     C instead of fortran function "riempi": great improvement in
39     C time processing!!
40     C
41     C 3.1.00 - 3.2.00: (2004-10-13) forget to clean some variables, fixed.
42     C Reprocess event in the case we have CRC errors and a high
43     C number of error trying to understand the kind of event
44     C we are processing (raw, compress, full mode) in order to
45     C distinguish better the four section.The reprocessing happens
46     C on about the 30% of events with CRC errors (in the case of
47     C file 040827_005 the reprocessing is done on about 2% of all
48     C the events).
49     C
50     C 3.0.00 - 3.1.00: (2004-10-12) cleanup and speedup of the code, less loops
51     C same strength in finding the calorimeter sections.
52     C
53     C 2.18.4 - 3.0.00: (2004-10-07) major changes in the procedure to find the
54     C calorimeter sections and enhanced search in the case of
55     c CRC errors (to fix a bug which made the misunderstanding
56     C some kind of CRC errors with missing sections).
57     C Clean up unused variables, speeded up some loops.
58     C Zero length input vector error added.
59     C Enhanced search of the first section recorded since the
60     C starting point is very important to correctly find and
61     C interpret all the other sections.
62     C If section length is absurd and the CRC header bit = 0
63     C then search again for that section (needed to make a
64     C better search of section when in presence of CRC errors)
65     C Search all the sections and if you reach the end of vector
66     C (EOV) continue searching if you haven't find all the four
67     C section (and go out without looping if no section is
68     C present).
69     C
70     C 2.18.3 - 2.18.4: consider a bad thing if you find a section in the wrong
71     C position of the vector and try again to
72     C find the real data (if they exist).
73     C
74     C 2.18.2 - 2.18.3: vectors belonging to common must be cleared if the calo
75     C isn't found. Fixed.
76     C
77     C 2.18.1 - 2.18.2: fixed unclearing error codes if the program doesn't find
78     C the calorimeter where it should be but shifted somewhere
79     C else forgotten to clear st2c variable: fixed
80     C exit error code wrong in some cases: fixed
81     C self trigger data not saved: fixed.
82     C
83     C 2.18.0 - 2.18.1: small changes in the common varie to fix a memory leak;
84     C fixed an error in reporting error codes (stwerr,pwerror).
85     C
86     C 2.17.0 - 2.18.0: corrected bug which made unable the program to find CRC
87     C errors in the last section of the calorimeter;
88     C added a "debugging" option to dump to standard output
89     C the whole packet in hexadecimal format and other
90     C useful informations. To activate it the dump variable
91     C in the common varie must be passed with the value
92     C of iev you want to check. Do nothing if you don't want
93     C any output.
