2001/10/10 Version 1.3: in dap4.c, functions "effects"
           and "ftest" now check types of variables
2001/10/09 Version 1.3: fixed bug in dap3.c: in function
           "plotlinreg", length of variable "srtarg" was
           1 too short.
2001/10/01 Version 1.3: Added statistics to function
           "means": VARM (variance of the mean with
           df = number of observations - 1)), VARMFREQ
           (variance of the mean with df = sum of
           weights - 1).  Updated dap_make.h
           accordingly.
2001/09/28 Version 1.3: Removed clumsy function
           "dap_param"; now header file dap.h does
           #ifdef to determine whether user defined
           parameters ABOVE #include <dap.h>,
           otherwise sets defaults.
2001/09/27 Version 1.3: Write errors to .err file,
           report lines read, written to .log file;
           only display .err automatically.
2001/09/26 Version 1.3: Fixed bug in function
           "dap_rest": incorrect reference to do_in
           list.
2001/09/26 Version 1.3: Function "step" now reports the
           file name in which an error was encountered.
           On end of file, "step" also reports, in the
           log file, the number of lines read.
           Appropriate log lines are now labeled with
           "ERROR" or "WARNING".
2001/09/24 Version 1.3: Fixed bug in function "dataset":
           clearing values of variables in oldname that
           are not in newname.
2001/09/24 Version 1.3: in dap2.c, incorporated weighted
           percentiles into function "pctile" by (1) adding
           a weight variable and values, (2) calling
           "dap_mnsparse" (renamed from "meansparse" and
           no longer static in dap1.c and entered into
           dap_make.h), and (3) calling the new function
           "pctile2" if weighting is present.
2001/09/15 Version 1.3: Renamed "probn" and "npoint" to
           "probz" and "zpoint", resp.
2001/09/15 Version 1.2: In src/dap3.c, function "plot1",
           changed title0 to static, allocated once, don't
           free.
2001/09/15 Version 1.2: Renamed functions "invprobchisq",
           "invprobf", "invprobn", and "invprobt" to
           "chisqpoint", "fpoint", "npoint", and "tpoint",
           resp.: src/dap[345].c, src/prob.c, src/dap_make.h,
           src/dap.h, doc/dap.texi
2001/09/14 Corrected a bug: function "invprobn" was
           returning the negative of what it was
           supposed to: src/prob.c Fixed calls to
           "invprobn" in src/dap3.c and src/dap5.c
           accordingly.
2001/09/14 Changed src/dap3.c: added parameters "marks"
           and "nmarks" and added variables "plotmarks"
           and "pn" to functions "plotlinreg" and
           "plotlogreg" so that they could process files
           that are partitioned. Updated doc/dap.texi and
           examples "ms95.c" and "cda88.c", and their
           output accordingly.
2001/09/06 Changed unsigned's to unsigned int's in
           src/machdep.c
2001/09/06 Setting dblhigh, dbllow moved to main() from
           inset(), outset() in src/dap0.c
