XSubject: VMS SC
X
XVMS USERS:
X
XBob Bond has been generous enough to give me free rein in adding what I
Xthink is needed to make SC run on VMS. Any problems with VMS should be
Xdirected to me--they are not Bob's fault.
X
XThe VMS SC is "SIMPLE" for the most part, except that the arrow keys
X(instead of hjkl) will move you around the cells. The VMS version of SC
Xwill not interact with the Bourne shell (obviously), which means that CRYPT
Xand EXTERNAL FUNCTIONS will not be available.
X
XIf you have a 'C' compiler and GNU Bison then you should be able to get
XSC running on VMS by following the instructions below.
X
XStep 1: Get all the files
X
XI've heard of a few sites that can unpack unix shar files directly on
XVMS. Most people, however, will need access to a unix machine to get
Xthe original distribution unpacked. At this time you should also build
Xexperres.h and statres.h and perhaps run the man pages off if you need
Xto port the documentation. To build the two "missing" hearder files:
X sed <gram.y >experres.h -f eres.sed
X sed <gram.y >statres.h -f sres.sed
X
XStep 2: Cut out BUILD.COM and GETOPT.C
X
XAt the end of this file are two other pieces: BUILD.COM and GETOPT.C. After
Xyou've moved everything to VMS, cut BUILD.COM and GETOPT.C out of here and
Xput them in the same directory as the rest of the SC distribution.
X
XStep 3: Build it
X
XTheoretically all you now need to do is @BUILD and SC (as well as PSC)
Xwill be running on VMS. If you have problems feel free to contact me
Xat ...!arizona!naucse!jdc (or even call at 602-523-6259).

X.SH DESCRIPTION
X.I Ppname
Xis used to prepare data for input to the spread sheet calculator
X.I pname(1).
XIt accepts normal ascii data on standard input. Standard output
Xis a
X.I pname
Xfile.
XWith no options,
X.I ppname
Xstarts the spread sheet in cell A0. Strings are right justified.
XAll data on a line is entered on the same row; new input lines
Xcause the output row number to increment by one. The default delimiters
Xare tab and space. The column formats are set to one larger
Xthan the number of columns required to hold the largest value
Xin the column.
X
XOptions:
X
X.IP "\-f"
XOmit column width calculations. This option is for preparing
Xdata to be merged with an existing spreadsheet. If the option is not
Xspecified, the column widths calculated for the data read by
X.I ppname
Xwill override those already set in the existing spreadsheet.
X
X.IP "\-L"
XLeft justify strings.
X
X.IP "\-k"
XKeep all delimiters. This option causes the output cell to change on
Xeach new delimiter encountered in the input stream. The default
Xaction is to condense multiple delimters to one, so that the cell only
Xchanges once per input data item.
X
X.IP "\-r"
XOutput the data by row first then column. For input consisting of a single
Xcolumn, this
Xoption will result in output of one row with multiple columns
Xinstead of a single
Xcolumn spread sheet.
X
X.IP "\-s cell"
XStart the top left corner of the spread sheet in
X.I cell.
XFor example,
X.I "-s B33"
Xwill arrange the output data so that the
Xspread sheet starts in column B, row 33.
X
X.IP "\-R n"
XIncrement by
X.I n
Xon each new output row.
X
X.IP "\-C n"
XIncrement by
X.I n
Xon each new output column.
X
X.IP "\-n n"
XOutput
X.I n
Xrows before advancing to the next column. This option is used when
Xthe input is arranged in a single column and the spread sheet is to
Xhave multiple columns, each of which is to be length
X.I n.
X
X.IP "\-d c"
XUse the single character
X.I c
Xas the delimiter between input fields.
X
X.IP "\-P"
XPlain numbers only.
XA field is a number only when there is no imbeded [-+eE].
X
X.IP "\-S"
XAll numbers are strings.
X
X.IP "\-v"
XPrint the version of
