BUGS FIXED IN MVSP SINCE VERSION 2.0
4 Nov. 1990
Ver. 2.0 released
6 Dec. 1990
Fixed bugs reported by John Breen:
Install didn't recognize 80x87
Entering more than two characters for drive to hold
temporary files caused garbage to be printed to screen.
8 Dec. 1990
Fixed another bug reported by John Breen: Stack overflow
in Distances procedure with Spearman and 80x87 version,
occurred when RANK_DATA called.
Released as Ver. 2.0a.
26 Jan. 1991
Fixed install procedures; bug reported by David Franz.
Installing program on dual floppy disk computer (no hard
disk) caused "File not found" error when trying to
unarchive program files.
27 July 1991
Fixed bug in cluster analysis reported by Chris Hardy.
Clustering of large (692x692) distance matrix gave "Big
Array error, insufficient memory to create Big Array
data pages" when trying to create temporary files.
Released as Ver. 2.0b.
13 Aug. 1991
Fixed bug in Install reported by Jack Wolfe (& David
Horsfield previously) in which disks with large amounts
of space (> 32Mb) were reported as not having enough.
Fixed problem resulting from bug fix of 26 Jan. 1991; none
of the files were being extracted from the MVSPUTIL
archive.
5 September 1991
Fixed bug reported by Al Traverse & Dale Beeson; heap
overflow error in cluster analysis.
Released as Ver. 2.0c.
11 September 1991

error after saving file in data editor. This only

1
29 February 1992
Modified PLOT14 so that Postscript output is prefixed with
"%!PS-Adobe-2.0" for fussy printers.
14 March 1992
Fixed problem with SORTDATA where Bigarray Error
"Insufficient paragraphs allocated for RAM storage"
occurred when too much memory available (>600k or so).
22 July 1992
Fixed bug with install program. It wasn't recognising
that machines had math coprocessors installed and thus
wouldn't install MVSP87.EXE. Caused by different factor
than similar bug of 6 Dec. 1990 (change in new
compiler). Bug reported by P.A. Jones.
23 November 1992
Fixed bug in SORTDATA. If data file has same number of
rows as columns, sometimes reported Sortdata would
report that order files didn't match data file. Bug
discovered by Catherine Duigan.
14 January 1993
Fixed bug in MVSP, reported by Matthew Wills.
"Eigenvalues not equal to trace" warning in
eigenanalysis. Occurred with data matrices that almost
completely fill memory. Similarity matrices were being
corrupted by memory management problem. Temporarily
fixed by forcing all analyses to dump data to temporary
files.
Released as Ver. 2.0f
1 June 1993
Release of MVSP ver. 2.1. Besides adding several new
features this version fixes a few bugs:
In the correspondence analysis procedure, if some type of
transformation (e.g. log) was chosen, the column and row
totals were being calculated before the transformation,
not after, thus giving inaccurate results.
If any of the .BGI video driver files were set to read-
only, they could not be opened and graphics would not be
displayed. Added routine to check and to change any
read-only .BGI files to read-write.
Discovered and fixed core problem in the 14 Jan 1993 bug
reported by Matthew Wills.
