Here are some utility programs used by VPW. The curve fit mainline is 
provided.  Unfortunately, to rebuild it you need access to a licensed
software package.  However, CURVFIT should run on your system on either
Tektronix 4014 terminals (/FT1) or /REGIS terminals.

SWAPXY takes our canonical X-Y data file and swaps X and Y data.

TYPEPAGE displays text between two line numbers in a text file.  It is
used by VPWTOOLBX.

CURVFIT does all kinds of curve fitting.  More to come one day I hope.

CNVDCALXY converts a DECALC dump file into our canonical X-Y format

MAILMSG is used to give VPW a symbol showing how many mail messages
are waiting to be read.  This version works with VMS V4.0 MAIL only!

LN03 is used to convert RUNOFF output for an LN01 into suitable format
for an LN03 printer (only bolding and underlining are considered at this
time).
